Seems like a pretty crap situation all around.
The kid's background and age make his reaction perfectly understandable. The lack of an outlet to protest is a good point too. I don't think a funeral, specifically, is the right place for it, out of consideration for the family less so the police. (and, in this instance, given the nature of the officer's death- it's even worse, as the feeling of hatred toward your loved one already has to seem pretty toxic even before the music) The officers barging in without right is pretty disgusting too, though, whatever I think of the NYPD aside, I can at least get getting angry at the sound of protest music at a coworker's death, especially if they were friends or close in anyway. Still, I don't think the teen deserved any punishment, much less eviction. At least this news will give a previously voiceless kid a voice for just a moment, so there's some silver lining to all of this.
