You can sue a thief, a trespasser, a batterer or assault-er--it's what they did to OJ after the criminal courts failed. It's called an "intentional tort". Check your homeowner's policy--you're not insured for an intentional tort. You can't punch a guest in the nose and expect your insurance to cover you.
And there's such a thing as being complicit in an intentional tort--like aiding a dangerous trespasser, helping (or seeming to help) someone to get false ID--
I've wondered if ranchers on the border could go after those who help illegals trespass and trash up their property...like these do-goody church leaders.

IMHO, fraud is a “crime”, at least as perceived by most of the public. Such a violation of law can result in criminal or civil liability, or both in some cases as with the OJ. In California, under current law, a third strike, as with unlawful breaking and entering three times by the same person or persons is considered a felony.
