That's not what the law says though. It only says that if I'm renting to you and I find out that you're cooking meth I should evict you; not that I should refuse to rent to you because I heard you've cooked meth. I'm responsible for meth being cooked on property I own, whether it's me cooking or not.
In the same way, if I find out you're doing something illegal (file sharing for example), I should stop you.
