drug dealer in home

[Rall Hanna]

Please assist....I have a drug dealer for a tenant. I actually saw the person dealing. My immediate reaction was to call the police and evict him. Then...several things came to my mind.

a) If I have him arrested, retaliation against me is possible and sever retaliation against my property is inevitable.
b) Just because somebody is arrested doesn't mean I can evict them. Yes, he is doing illegal stuff in my home. But I have no proof other than my word against his.
c) As an alternative, I could just ask him to leave because I know he is doing illegal stuff...........

Thoughts? I would love to kick the guy out without letting him know I'm doing it because he is a drug dealer....I value my personal safety as well as the safety of my investment........
