Truth is, he probably laid way low... got him a job at the station years later and nobody even thought about it, except for those who knew who he was. I doubt dude was randomly bringin' it up and letting people know about it. If he was THE guy being pointed at in the murder, they probably woulda remembered who he was, but if he's just up there goin' by "Paddy Duke" and nobody remembers him from the Hawkins murder cause he was just one of the kids with bats... I can see how he could be low-profile without these artists or personalities knowing.
But yeah, now that this is out, somebody gotta address it. NOT saying anything about it means A) they tryin' to keep it buried, or B) they're bein' "influenced" not to say anything about it.
