The sad part is that if the cop would have simply opened the door and shown his BADGE... The rider (who may be a rational guy, though this isn't evidenced by his riding) may have just shut off the bike, camera, and removed his helmet to accept his ticket. Or maybe he could have just allowed the officer in the marked car (who's probably wearing a uniform) make the arrest... I mean, it's not like he's going to get a commission for closing the arrest or anything. I mean honestly... If you're riding along, and someone emerges from an unmarked car with windows that look like they were painted black, brandishing a semi-automatic weapon... Would you expect that cat to be law enforcement, or someone who's about to put two in your chest and ride off with your sh*t? ESPECIALLY in MD!
