Classic reflex shooting situation+everyone around assumed a threat = supporting fire. Multiply by everyone around who fell into it, and you have a lot of firepower thrown around... in that case, without reasons.
Put a US cop or any other country cops with a gun in his hand, in the same situation (robbery+chase+showdown and no indication on armed or unarmed), you would have the same result.
I'm saying this but I still find it funny in a macabre way, how US already ends up being on the spotlight each and everytime.
No video of it btw?
they have the weapons in the trunk locked with a key they themselves have to unlock, meaning they can't draw a pistol from their belt and be nervous pussies and shoot without checking.
Obviously stupid solution that only works in 0 crime areas.
