Great topic......
Not sure I even know what side I am on, I could argue both ways as I sure most level minded people could.
The one thing I know for sure is if this is a true story and it happened to me I would be so pissed that I would have been down at the police station to file a report 2 seconds after it happened. If his actions were justified for some reason none of us know, so be it, but if they were not his superiors need to know.
They have a tougher job than most people think, while most of us learn not to go down that dark alley that was pointed out earlier, cops are forced to.
