Police say he never told them the true intent of his film was to test their response.
The YouTube video that has gotten more than a thousand hits speaks for itself. An alarming sight -- a man wielding what appears to be a rocket propelled grenade, standing in the intersection of 33rd Avenue and Bell.
According to Turley, this was a test to see how quickly police would respond to the threat. It occurred days after the tragic shooting inside a Colorado movie theatre.
Turley was arrested Monday in connection to the stunt.
"Imagine driving the street on Bell Road and you see someone pointing a grenade launcher," says Phoenix Police Officer James Holmes.
"What if one of those citizens decided that this peson dressed as he is, with that rocket decided he was a danger to him and decided to run over that child?"
