I'll try to keep this vague because I don't want to be identified.
I've just found out that someone I know (not a close friend) is a convicted paedophile. Done very harmful and disturbing stuff. Found it reported in a local newspaper. I'm sickened because he's offered to babysit for me before (we refused). He's got a suspended sentence so isn't in prison.
We aren't close but we have some mutual friends who are closer, including his best friend. If we tell them, is that breaching his (the paedophile's) right to privacy? It is reported in a local newspaper for anyone to see, but isn't a famous case, chances are they'd never see it if we didn't tell. None of the other friends have kids.
My instinct is I want people to be told. I wouldn't tell his employer, just closest friends. But I'm not sure what's right.
I'm a bit emotional about it (mostly angry and scared).
