In the 80s allegations of Satanic abuse in pre-schools set off an hysteria that led to over 200 people being charged and dozens convicted (some being released in 2013 and successfully suing for wrongful conviction). “When people get emotionally involved in an issue, common sense and reason go out the window. People believe what they want and need to believe.” said former FBI agent Ken Lanning. But we are hearing this sort of charges circulating again, and since even ridiculous charges can ruin lives, what should we due to guard ourselves, and our society against another hysteria?
