oddly enough, it happened in Massachusetts of all places, a state i expect to take this sort of hateful crime more seriously. maybe it would nowadays. that particular violent attack happened a while back.
regarding licensing: the rumor i heard (for what it's worth) was that Wahlberg recently wanted to become certified as an actual officer on a local auxiliary or reserve police force for some new show he was planning. but, as a convicted felon, he is not eligible.

It sounds more like a bad disaster movie than recent American history.
