pure BS. That fat kid could have been stopped by a punch, let a one shot from 9mm. And that even if he was attacking the officer, which he wasn't to start with.

Again, there wasn't need to kill, yet there was a right to do it - kid stupidly resisted harassment and even tried to move away ("run" in official language as he couldn't really run due to the fat) - and officer executed his right as they usually do to send the message that even minor disobedience will be severely punished.
