Again by your simple logic, anyone who is trespassing on private property while in their own private vehicle, could not be prosecuted for trespassing because, being in their private vehicle constitutes being in or on their own private property. By this logic I can park a RV on your property and not be trespassing on your property, since my RV is MY private property. Now do you see how asinine your argument is?
No. Look, you may not be smart enough to figure this out. But here goes. If I invite you to come to my house, it does not give me the right to go through your car when you get here. Or your wifes purse. Or your wallet. Or do body cavity searches on you. As long as anything I would object to STAYS in your car, wallet, purse, or lower GI tract, why should I care or have a Right to know?
Just because me or my property is on your property does not give you unlimited ownership Rights of that property. The most you could do is recind the invite and tell me to park elsewhere.
Of course, none of that supports your anti gun agenda, so no I guess you'll either twist what I just said or take the whole thing off in another direction. Again. You people are pathetic. Get some help...
