Have you never used courtview?  A woman answered my ad for a roommate.  I check her out on courtview and she was stunned that I found her record and that she had a warrant for her arrest.  I also got a response from a woman in NC so I check their courtview and found that she had a long list of jail time, DWIs, and such.  She never responded when I copied and pasted the information about her and emailed it to her.  Not that she had not gotten sober, she may well have, but I was not in a position to find out.  I had a roommate that I wished I had checked on.  She was a raging alcoholic.  Not all states have this info available but I do use it when I need to.  I checked on an acquaintance not long ago because I sensed something was not quite right.  I was correct in my intuition.
