I don’t know if this guy is a cop or not, but it looks like he bought some space for innocents to escape. He’s far more restrained with that gun than I would be. I wouldn’t bet I’m quick enough on the draw to pop that dude with the bat if he were to come at me, and I’d have drawn and aimed at batman once he got that close. But if he’s not a cop, he’s probably carrying that piece illegally, and that might be the reason for restraint. I also don’t speak French, so likewise that makes it hard to understand.
Police officer or no, confronting a band that size wielding deadly weapons, badly outnumbered, armed with just a pistol takes some gonads.
