You'd be surprised. Alot of people on the mainland are gun nuts, and alot of people on the mainland are obsessed with celebrities/popularity/fame/stardom/etc.
Infamy is a quick way for those types of losers to use the only and only thing they're good at (guns) to obtain the one thing those forgettable, lonely, scum desperately want: fame.
So therefore, they'll always will be remembered.
That's why John Lennon was shot by that sad sack of shit. As he once said so himself:
"I knew what I was doing, and I knew it was evil, but I wanted the fame so much that I was willing to give everything and take a human life."
Sorry for going a bit off -topic, I just wanted to answer the question.
Alright, moving on to a much more worthy, rememberable, sympathetic, folk hero.
