It's the fact that David manages to keep the alarm from going off that solidifies the idea that he's a hacker, too, in Aiden's mind. For all he knows, though, the kid's Prime_Eight or one of the various gangs' people or any number of things, so he's still fair game. They can sort it out later, once he has him pinned down, and so he shoves something nasty and loud at David's phone. If it works, well, his ears won't be happy. Shouldn't have put those headphones in, kid.
