You wont be interested in the arguments he has with a grand jury later.

Personally I wouldn't always resort to armed confrontation until the person has shown himself to not want to leave. I just don't like escalation to be done by myself...that said, I don't think he has a right to be on your property if you gave him notice by sign or verbally. My "shotgun notice" was a bit of a joke legally, but practically I think it's true.
