How can I find out if my roommate has a criminal history? Can I go to the courts for it?
You can check at the local courthouse and for some like mine there is an on line index.
If you have reason to be concerned about it you should move out.
Well, when you share a prison cell with someone, you should expect that they have a criminal history. You can sue, but it probably won't do any good.
Some states have the information on line for free, courthouses also have public records free but only for their jurisdictions. Online background checks can be done for a fee but verify the information, they are not all that accurate.
He screamed in my face yesterday, and he kept telling me I can't sit in the front pourch, or I can't bring anyone to the house. So he has high demands. He also threatened to shoot me if I stole from Jim, but then said he was joking. But people don'tont joke like that He needed help paying his bill, so he overcharges people
No. As a private citizen you aren't entitled to know.
