Sorry, but you’re wrong on this. The officer pulled the taser out DURING the first instance of saying “Turn around...put your hands behind your back”. He did NOT wait until the driver was non-compliant to that first command before pulling out his taser.
The thing about this video, though, is that we know the context. The driver was from the beginning resisting proper authority, and his wife was contributing to the stress.
I emphatically support this cop.
