Just to repeat something I said upthread. Facebook doesn't 'scrub' pages like this. They just make them private so only law enforcement can access them. This is to protect friends and family of the perp or victim but also to keep trolls from vandalizing the page.
Just because you don't see it now doesn't mean there is a nefarious conspiracy to erase some content.
Also, within minutes of most of these incidents, trolls make fake accounts like mad, so unless there is a paper trail (so to speak) be very diligent in what you trust. We have no clue, for example, that bong shirt guy is him or from a fake account that was pulled.
