Sex offenders are everywhere, though. Not to dismiss their vileness, but there is an element where society holds them to a different standard than any other kind of convicted felon. People love to cite the wive's tale of recidivism being the reason for this exception -- i.e., where doing your time is not sufficient and you're forever a modern leper of sorts. Statistically, it turns out that it's overblown compared with other crimes.
Thus my point being is that while we ought to be careful, the truth is you've lived in close proximity with convicted sex offenders for decades and didn't notice. Researching it now might be good on who to look out for under the wrong circumstances, but you're bound to make yourself more paranoid and no safer.
What a waste of a good rape van.
Yeah, in London.
