That's because people show up to clap the 'goodies'. The argument works in reverse and everyone gets egg on their face - here in the UK we've just had a TV show released about Jimmy Saville.
If you speak to everyone in the UK they all know he was a wrong-un, could see it from miles away, when people say this - I always remind them that the man pretty much had a low-key state funeral in Leeds. Nobody showed up to protest and though there were people who obviously knew most of them did nothing.
The banality of evil be like that. :o)
