( CNN ) -- A man who paraded his cloaked 16-year-old nephew around a busy Phoenix intersection with a fake rocket-propelled grenade launcher was found guilty Monday on endangerment and terrorism hoax charges . Michael David Turley , 40 , posted a video on YouTube last year showing the teen walking around the streets covered in a sheet and pointing the fake weapon at cars . The video went viral with more than 250,000 hits . In the video , a man says he and an actor are trying to test how police would respond to such a scene at a busy intersection . Turley 's attorney , Brad Rideout , said the ordeal stemmed from some simple horseplay . `` He was in the house and the nephew put on the sheet and started fooling around , '' Rideout said . `` He took his still camera and started taking photos . He put up the video like he was testing the police department , but he really was n't . This was completely impulsive . He did n't intend to make the police come out . He did n't intend to make it look like a terrorist act . '' When asked if he thought 911 callers were actually scared , the attorney responded , `` If someone comes to your front door with a samurai sword on Halloween , you would still be scared even though it is Halloween . '' Turley faces up to five years in prison . Sentencing is set for August 8 .
