I'm with you here. It's not cut and dry unless you were there. If the cops killed him it seems obvious he was armed or presented a very significant threat to the police (not to mention the "cowardly" civilians). Is it cowardly to save your skin at the expense of others, even a child? Perhaps. You all know what an adrenaline dump is. I'm confident any witnesses are scarred for life and are well aware of their own guilty feelings for not doing (or feeling able to do) more. Many of us have seen someone in a blind rage, right? Even if they'd done something, what if the child was already dead? Would they be criticised for not doing something fast enough? If you intervened and killed the guy, it's not likely you'll go to jail but stranger things have happened, not to mention a lack of awareness of possible consequences not likely to occur to them when in a state of shock. I'm not defending anyone but remeber that people are human. We're not all heros. Those people may have had families of their own. FEAR CAN BE A POWERFUL THING.
