You do not know any facts unless you were standing there. To claim that the guy who was shot "didn't do anything" is presumptuous and wrong. Additionally it is irresponsible to say the least. We can argue over the measures of reasonability on the use of a fire arm, but absent the details of any event it is ignorant to declare whether or not something was right or wrong. Equally, given the guy wasnt initially held or charged, there is a strong implication the shooter was a perceived victim under the law.
