Unfortunatelly, the actual correct thing to do is call fish and wildlife to remove the cameras. why, because if the trespasser shows up with law enforcement at your house with serial numbers or some other distinguishable proof that they are his cameras then you could get a larceny ticket while he is getting his trespassing ticket. Since Im sure he knew he was on your property I imagine he has an idea where to find his illegally placed camera when it comes up missing. Sucks, but we law abiding folks have to do the right thing even if it doesnt feel like we are getting even.
Here you go...........Since you already have a cam out to catch them coming and going get their pics, photo shop them up with some banners like "trespasser", save the pics back on the cards, put them back in and let them come check their cams......to be a fly on the wall when they see their own pics coming and going from a different cam and the note "trespassers beware, cops already called" across their own pic......
tag... gotta see where this goes.
