Bruce Von Faulstich is a Security Professional, not a bounty hunter. He had been a former airport security person. Bruce Von Faulstich had an encounter with code enforcement at his property where he removed a code enforcement employee from his property because he had no legal right to be there. Shortly after this encounter, San Bernardino Police Officer Scott Roebuck received a search warrant for his residence based on an affidavit that falsely claimed he had a felony conviction.
A person with a felony conviction can not possess weapons. The problem is that Bruce Von Faulstich did not have a felony record.
Another problem with the court situation is that law enforcement officers who are in the audience are not supposed to have their arms in a courtroom. It appeared these backup officers were armed as they reached for their weapons.
