Paul Schlesselman, 18, of Helena-West Helena, Ark., and Daniel Cowart, 20, of Bells are accused of dreaming up the plan. While authorities say they had guns capable of creating carnage, documents show they never got close to getting off the ground.

Among the blunders: They drew attention to themselves by etching swastikas on a car with sidewalk chalk, only knew each other for a month, couldn't even pull off a house robbery, and a friend ratted them out to authorities.

"Certainly these men have some frightening weapons and some very frightening plans," said Mark Potok, director of the Southern Poverty Law Center, who studies the white supremacy movement. "But with the part about wearing top hats ... it gets a bit hard to take them seriously."

Despite making sure the plot was stopped, authorities did not believe Cowart and Schlesselman had the means to carry out their threat to assassinate Obama, said a federal law enforcement official who spoke on condition of anonymity because he was not authorized to discuss the case publicly.

Asked whether the two suspects had Obama's schedule or plans to kill him at a specific time or place, a second law enforcement official who also was not authorized to speak publicly said, "I don't think they had that level of detail."

The two met online about a month ago, introduced by a friend and bound by a mutual belief in white supremacy, according to an affidavit written by a Bureau of Alcohol, Tobacco, Firearms and Explosives agent who interviewed them. Together, they chatted about how they could carry out such a terroristic spree, officials said. Schlesselman volunteered a sawed-off shotgun that would be "easier to manuever," and also took a gun from his father, according to an affidavit.

The plot referenced two numbers important to skinhead culture by aiming to take the lives of 88 people, and 14 of them would be beheaded. The number 14 refers to a 14-word phrase attributed to an imprisoned white supremacist: "We must secure the existence of our people and a future for white children" and to the eighth letter of the alphabet, H. Two "8"s or "H"s stand for "Heil Hitler."

But that may have been as detailed as it got. Last week, Cowart drove to pick up Schlesselman from his Arkansas home so the plot could begin, according to the affidavit. They decided to start with a house robbery, and asked a friend to drive them. But when they got to the driveway, they saw a dog and two vehicles, and got spooked.

Armed with ski masks and nylon rope they purchased at a Wal-Mart, they tried again the next day to get started. Authorities say they decided to fire on the windows of a church, then bragged about it to a friend. She told her mother, who alerted the local sheriff. Investigators were able to trace the shell casings to the pair, and took them into custody after spotting their car, decorated with chalk-drawn swastikas and racially motivated words, along with the numbers "88" and "14."

Schlesselman's family said Tuesday that it was unlikely he was seriously planning an attack, even though he expressed hatred for blacks. A high school dropout who was unsuccessful finding work, he often spent time on the computer, his 16-year-old sister, Kayla said. She said she often argued with him about his racial beliefs, and he would say things like "Obama would make the world suffer."

He hated his tiny Delta hometown of Helena-West Helena because it was predominantly black, she said.

"He just believes that he's the master race," she said. "He would just say things like 'white power' and 'Sieg Heil' and 'Heil Hitler.'"

His father, Mike, also doubted the plot was serious. "I think it's just a lot of talk. He would never do something like this," he said.

Cowart worked at a grocery store in Bells for about a year, according to Scotty Runions, 54, who supervised him. Runions said Cowart was preoccupied with computers and bagged groceries at the store until about May 2007, before moving to Texas.

"The guy I saw on TV last night was not the same person that I knew, and I saw him about a month ago," Runions said. "This is something he's created in the past month - that's not the young man that we know."

The Southern Poverty Law Center traced Cowart to the Supreme White Alliance, a skinhead hate group organized this spring that describes itself on its Web site as a "Club based on Racial beliefs. and for those of you who don't know what that means, we are in fact Racist's."

But the link doesn't appear strong, and the group apparently kicked him out earlier this year. A post on the alliance's Web site accused the law center of lying about the extent of its connection with Cowart, but acknowledged that "one of the two young men was in fact a probate earlier this year but was ousted."

The group's leader on Tuesday condemned the plot and denied that Cowart had been a part of his "club," but nevertheless said he was resigning as its president over negative publicity the case generated.

"We don't go out and start trouble. We are more like a social club. We just hang out," Steve Edwards of Central City, Ky., told The Associated Press.

Potok, the law center's intelligence director, said Cowart is shown in a photograph of an April alliance gathering to commemorate Hitler's birthday.

"The chances are excellent he was booted out when he was in the news in a way that didn't reflect wonderfully on them," Potok said.

Attorneys for Cowart and Schesselman haven't commented, but Schlesselman's sister said Tuesday she spoke with him after the charges were made public. "He said he's sorry about everything he's done," she said.

The plot was the third high-profile incident involving death threats against Obama in the last three months.

Raymond Hunter Geisel, 22, has pleaded not guilty to charges he threatened to assassinate Obama and President Bush. Authorities said Geisel kept an arsenal of weaponry and military gear and made the threats while attending a training class to become a bail bondsman.

A group of men who sparked fears of an assassination plot against Obama during the Democratic Party's presidential convention in Denver in August. Authorities said the men had guns and bulletproof vests and made racist threats against Obama, but were high on methamphetamine and posed no true danger.

A judge dismissed the charge for lack of probable cause in July, but under the strict rules of the state's parole program, William Balfour could have gone back to prison just for the arrest.

No one has been charged in the shooting deaths of Hudson's mother, Darnell Donerson, her brother, Jason Hudson, and 7-year-old nephew Julian King, but Balfour has been named as a suspect. Chicago Police Superintendent Jody Weis said Tuesday he is confident the case will be solved.

Balfour - Julian's stepfather and the estranged husband of Hudson's sister - served seven years for attempted murder and vehicular hijacking. Court records show that in 1998 Balfour stole a Chevrolet Suburban and, with the vehicle's owner clinging to the top, intentionally rammed it into a light pole, fence and iron gate.

According to a Chicago police report, officers pulled Balfour over June 19 after hearing gunshots and seeing his car moving at a high rate of speed. Inside the vehicle, police said, they found a rock of cocaine with a street value of about $100 on the driver's seat.

Balfour's parole history report indicates a parole supervisor declined to issue a warrant to revoke Balfour's parole after his arrest for possession of cocaine.

"Per supervisor ... no warrant," the report reads. "Agent to monitor offender, impose sanctions."

Corrections Department spokesman Derek Schnapp said officials determined "the evidence that was presented during that time wouldn't have necessarily warranted a violation."

Court records do not indicate the reason a judge found no probable cause for the drug arrest.

A felony arrest usually is enough for Corrections to revoke parole, said Thomas Peters, a Chicago criminal defense attorney who represents parolees.

"Even though the criminal case is dismissed does not mean that you necessarily get a pass on a parole violation because the standard of proof is much less," Peters said.

Peters added, however, that officials also would have considered Balfour's fairly clean record as a parolee and that he apparently still had a job. In addition, he said, jail and prison overcrowding often play a role in determining whether parole is revoked.

Donerson, 57, and Jason Hudson, 29, were found in their home Friday afternoon. The body of Julian, who lived with the other victims, was found in the back of an SUV on Chicago's West Side on Monday. Authorities declared his death a homicide Tuesday but would not say how long he had been dead.

In a message posted on her MySpace.com page Monday, Julian's mother thanked people for their prayers and said her son's "lil soul is at ease."

"I take comfort in knowing that Julian is with my mother and my brother and most of all the Lord and now he's my angel he's protecting," Julia Hudson wrote.

Jennifer Hudson, who won a best-supporting-actress Oscar last year for "Dreamgirls," has thanked fans for their support on her MySpace page but has been in seclusion in Chicago.

Around the time the first bodies were found, Balfour's parole agent had reached him by phone after Balfour missed a meeting with him that day. Balfour told the agent he was "baby-sitting on the West Side of Chicago," according to internal parole records.

The agent said he thought he heard a child in the background during the call. Balfour was taken into custody later Friday.

The Illinois Department of Corrections issued a warrant for Balfour on Saturday for violating terms of his parole by possessing a weapon and failing to attend anger management counseling and a substance abuse program, according to his parole history report.

Criminal charges can send parolees back to prison and keep them there even if the counts are ultimately dropped. A board that reviews such cases after parolees are sent back to prison relies on a preponderance of the evidence, a lower standard than in court. The board considers the violence of the original crime, the parole agent's recommendation, the arrest report, the parolee's adjustment and his attitude during a follow-up interview in prison, among other things.

In Balfour's case, a violation could have sent him back behind bars for a period as long as the remainder of his parole - until May 2009 - minus a day off for each day of good behavior. That would have meant a release date in mid-December at the earliest.

Parole records also show that a woman at Balfour's home refused to open the door during an agent's visit on Aug. 27. The woman told the agent during the 8:30 a.m. visit that Balfour was at work but Balfour's boss told the agent he wasn't due until noon.

"Agent heard other people inside the host site and suspected maybe suspicious activities going on," the report said. "Agent will be following up for a possible warrant on parolee."

Parolees must agree to allow agents to visit their homes and consent to searches. There's no warrant mentioned in following days on the report, which does note, however, that Balfour passed a drug test.

Schnapp, the corrections spokesman, said the evidence again wasn't sufficient to warrant revoking parole.
