[ATREYU]

In the blink of an eye, so cop will not stop to see if it's real or not, he will defend himself from what he sees as a threat to his life. If he were to stop everyone who had what looked like a firearm in his hand to inspect it to see if it's real or not, he'd be taking his life into his hands the one time it was real in the hands of someone who was ready to use it. He just wants to go home at the end of the day, and anything that looks like a threat to that will be dealt with using whatever means he deems neccessary, including shooting you. Contrary to popular belief, cops DO NOT want or like to shoot people, and most find it traumatic to have to do so (afterwards). Don't put a cop in a potential spot. He has a family same as you that he'd like to go home to.
