A lot of people would be happy. There are plenty of anarchists and communists and terrorists and gang members who would like nothing more than to see police officers being shot and killed on a regular basis.
And quite frankly, advocating destroying a man's career over an incident like this is tantamount to wanting to see him dead. People quite often commit suicide when their careers are destroyed. Their lives are permanently ruined, whereas this perp's life was temporarily inconvienienced.
You have advocated firing these fine young men based on nothing more than reading this thread and vieiwing a video that, quite frankly, shows a perp with an attitude resisting arrest and otherwise taunting the police to do exactly what they did.
What do you do for a living? Anything? Or do you just sit here online and condemn police officers all day?
