I have to disagree with you Ian, unless you were there how can anyone possibly comment on the actions of the officers from grainy piss poor CCTV.
Maybe the two officers were sent to a call to a person armed with a firearm pointing at members of the public.
Maybe the officers saw a person who they were informed was armed reach behind him for what they belived and were informed was a lethal firearm.
Maybe just maybe those officers fired in defence of their own lives because they belived an armed person was reaching for a weapon.
Maybe those officers wanted to see their kids that evening, pay the mortgage that month, do that bit off painting in the garden.
Maybe they didn't want their wives to explain why Daddy wasn't coming home. To why Christmas would be full of awkward silences and red eyes.
Behind the body armour and cuffs and unform we are humans too, just as scared and vulnerable as every one else, yet coppers head towards the gunfire, the knifes, the casualties, because at the end of the day they care.
