Colorado Man Built Pipe Bombs To Defend Himself Against 'Clumped Up' Guys in Front Yard, FBI Says

A self-described bomb-making novice from Colorado was arrested May 1 after federal agents found four homemade pipe bombs in his home.

The man, Bradley Bunn, 53, said he was worried about people storming his home and was preparing for that possibility.

"I don't have a lot of experience in this. I haven't done this before," Bunn told an FBI special agent, according to court records.

"I bought this stuff at Jax," Bunn added.

Bunn is accused of violating federal law prohibiting the possession of unregistered explosives. As a private person, Bunn would not be able to register any such devices under the National Firearms Act, which effectively prohibits their home manufacture.

According to ABC News, Bunn caught the attention of federal law enforcement officials ahead of a planned May 1 rally as an instigator of anti-lockdown protests. He was reportedly encouraging protesters on social media to bring semi-automatic rifles to the rally at the Capitol building in Denver.

Leading up to the rally, the tone of Bunn's social media posts became increasingly aggressive, ABC News was told, and the FBI quickly learned that Bunn may have been harboring pipe bombs.

A lawyer for Bunn declined to comment about the allegations. If convicted on the registration charge, he faces a potential penalty of 10 years in prison.

According to a criminal complaint filed in the case, FBI agents conducted a search of Bunn's Loveland, Colorado, home early in the morning on May 1. They discovered "four devices that consisted of a galvanized steel pipe with external threads and an external end cap on each end. One end cap on each device contained a hole through which a fuse had been inserted as an initiating system," the document said.

Bomb technicians later learned that the filler inside the devices was explosive. An FBI agent asked Bunn whether it was smokeless or black powder, two types of gunpowder. According to the affidavit, Bunn replied, "I don't know, I'm a dumb**s with this. I don't know."

He added: "Because I don't know much about this stuff, I don't exactly know what went into the device that I built. That's the best that I can tell you."

Bunn told an FBI agent that he was testing the devices for accidental combustion by throwing them onto the ground to make sure they would not detonate unintentionally.

Asked if he put fragmentation materials, such as shrapnel, inside the devices, Bunn replied that he "was considering buckshot" but did not end up following through, according to the affidavit.

"I mean if you're gonna do a job, do it right," he said. "But because I don't have the sufficient knowledge to know what interacts with that, I didn't want to...cause some kind of chemical reaction I didn't expect."

The FBI said Bunn explained that he assembled the bombs in order to guard against a potential home invasion. If his residence were to be stormed at 3 a.m., Bunn said, he wanted to be ready to neutralize a group of "clumped up" guys in the front yard.

He did not say why he was worried he would be a target of those men.
