Nothing wrong with those actions in my opinion based on what I've seen so far.
Exactly how is someone not trained to panic ?
because training scenarios are in no way comparable to real life for a multitude of reasons. I understand they're developed for the purpose of replicating real life scenarios as close as can be, but it's not the same.
those criticising the police, instead of being cowards how about you join up and be the change you so desperately seek ? That would require many of you to stop being a coward
