So sad to see this, as I said before it must be heartbreaking for the victims and their families to watch this.
They (cops) had numerical superiority and superior firepower, as you said, stack breach, bang and double tap the fucker.
Just look at all the kit they had, the average US cop is better equipped than the average British infantry soldier lol.
We hosted some American cops here in the UK as part of the IPA (Intl Pol Association) exchange program and the US cops couldn't understand how we police without guns.
The visiting cops couldn't understand why or how British cops police without guns on a daily basis.
Thing is, comparing the UK to US policing model is an unfair comparison because the amount of handguns in the UK is lower compared to the US, whilst we do have firearms incidents these are few and far between.
But our cops do tend to be a little more rational and proactive, I fear in the US a lot of people become cops because they are what we in England call "badge heavy".
