Is This A Pigeon

He was asked to defend property by the owner. As for killin' people, those three men chased him and attacked him. That's self-defense, not vigilantism.

Why did they attack the city?

They attacked Kyle Rittenhouse because HE USED A FIRE EXTINGUISHER TO PUT OUT A DUMPSTER FIRE THEY WERE TRYIN' TO ROLL INTO A GAS STATION. Why the Hell are you and the rest of the Left tryin' to defend these three rioters? The first man Kyle shot was a convicted pedophile, the second Darwin Award winner was a f**kin' psychopath, and the third was a convicted felon who admitted to pointin' a pistol at Rittenhouse when he was on the witness stand. They're the ones who should be condemned and demonized, not Kyle Rittenhouse.
