Contrafarming is Getting Worse.

Question: If I found something like Zzzzap's pic, would I have the right to raid?

I would assume not, because you have no viable proof. For all you know, someone else other than the owner could have put that sign there. If you happened to see any contraband, though, or had first hand information from an informant or such you could act on that information.
