Are you aware that if people bring drugs on to your property you can have your property seized by the government as evidence? That's true of other crimes as well. It's not only your right but your responsibility to know what goes on on your property.

You are confusing apples and oranges. Because you CAN, by law, have your property seized if someone brings drugs on there (if left in their vehicle, I'd say this is unlikely) does not make it RIGHT.

That does it. I will take it to the extreme. No one may come on my property unless they are naked and submit to a full body cavity search every morning.

If by law you must refrain from searching their person and property and thus are unable to ascertain their possession of drugs, you should be able to defeat the asset forfeiture. So this law, if it applied to drugs as well, would probably carve out an exception to their right to seize the property of a third party, at least in the parking lot scenario. If the third party was the owner of the VEHICLE, that might be a different story.
