Here you go. Click on the "Litigant name search" It will show you any thing the person has been to court for. Even simple traffic tickets.

That is pretty good. Thanks.
Sadly, it only seems to get Missouri courts. Federal and other states don't get a mention. It certainly didn't pick up all my tickets, but it did go back to 1993. I guess that is a start.
