Yes, taking off your hat and moving your hands is punishable by death.
Let's posit this- why did the police leave their vehicle with their guns already drawn? None of the three people there had any weapons drawn to begin with.
At the beginning of the second angle of the video, you can tell one of the suspects are reaching into their pockets for some reason, where officers couldn't see. Also, the call was placed as if someone's life was in danger. Exact quote:
GPD Officer Christopher Mendez was working as a uniformed patrol oficer. He was at the GPD station when a robbery call was broadcast via radio. The call was broadcast as a "3 beeper" priority call, meaning someone's safety was concerned.
It wasn't "some guy is riding away with my bike," they received information that someone's life could be in danger. That is a gun situation, reinforced when the cornered suspects keep ignoring orders and reaching into their pockets.
