I attended an event over the 4th of July weekend in Bristol, WI. I have a pickup truck with a cap on the back. The back was closed but not locked. Midway through the day upon returning, I found a note from security stating that they had taken everything in the back for security reasons and to go to the security office. Once there I was informed that my alchohol would be confiscated, but I could have my other things back. If I ever brought alchohol onto the property again I would be in trouble. They claim the tailgate on my truck was open and they had taken my things for "safe keeping" and found the alchohol while doing an inventory of it. The cooler is the only thing that was opened or "inventoried". While I cannot prove it, it is highly likely that they are the ones who opened the vehicle as nothing was missing and none who came with me had been out to the vehicle that day. They had one of their security people who was supposed to be Kenosha County Sheriff, but they where in security clothes, so I didn't bother asking for proof. I did call the Bristol police department and they said the only thing I could do would be if I could prove they opened the vehicle. Do they have the right to take my things from my truck even if the tailgate was down? Do they have the right to open my cooler or keep it's contents? All alchohol was brought for the weekend festivities and remained in the truck while on their grounds. We had driven in from Madison, WI and would be driving back after the event and had nowhere else to store the cooler while attending. Any advice is greatly appreciated.
