When there are members of the public around, you can't just fire blindly. I understand what you are saying but it's never quite that simple.
why would they need to fire blindly?
the police responded excellently and well withing any capability one could ask of their training
but they where never at any severe risk looking at that video.
random football fan or dude who thought bouncer was being attacked though where sales above them in terms of vulnerability and courage.
itys just 3 men with knives from a vehicle, with assault weaponry, hollow points and stab proof vests.
tyhwy where safe it would have taken unusual circumstances for any officer involved in that vid to be hurt.
