Dennis Nilsen lived up the road from me when I was a kid.
In a village I moved to when I was 10, a paedophiles house was set on fire with him inside and he died, no one was ever charged for that but there was A LOT of parents involved.
Same village, the local funeral director/ mortician was caught having sex with the bodies only because his girlfriend tested positive for an std that you can only get from a dead person after suffering with 'odd symptoms for a while.
In school, my teacher was caught "buying young boys" in Costa Rica when on his annual school trip to help the locals build houses. He was always a creep and showed us horrendous videos of animal abuse that I still struggle with now. He got life in prison for what was found on his computer.
Where I live now, too many, arson, murders, rapes, assaults, a lot of gang on gang crime. A family with several young children were murdered by arson in the early 2000s, the man fled the country and hadn't been caught.
Recently a child was murdered by machete for no reason other than being from a different country.
Another child stabbed outside
a school after a row.
Another child killed round the corner due to gang warfare.
The list is endless.
