I've been sent quite a few of them from real life friends and thought they were pretty funny. People in general don't want child molesters to evade the law just because they're rich or powerful politicians.
It is funny and it spreads fast because it's the first thing most people think in a high profile suicide like this.
My main point was that it is a meme/conspiracy theory that people who don't think they fall for conspiracy theories have fallen for big time.
