Supporting criminals

What are your thoughts on people supporting athletes/musicians/actors... so essentially famous people, after they have been convicted of a crime?

I feel like there are a lot of people that are quick to just forget and move on because it’s their favourite band etc

I have a friend who loves Chris Brown and I’m like... but how!!

And I am not talking like something petty, I mean sexual assault, assault, drunk driving etc

If you are one of those people who can forgive and forget easily, what’s your thought process or reasoning?
