I parked on campus (TOTALLY unarmed) today for class. I still had the GCO sign from the show in the back seat, as I did not have time to take it into the house last night. Visible on my backseat were the words "Georgia citizens' firearms rights". Now, I also have an NRA sticker and a GCO sticker on the car. When I got out of class, there was a University PD officer standing next to my car, writing down the tag number. I approached and said, "Officer XXX, that's my vehicle. Is something wrong?" as I presented my school ID (he's not getting my DL, as I'm not driving at this time). He said, "Yeah, we got a tip about a car with something related to firearms in it. What's that sign for on your backseat?" I said, "None of your business. Am I free to go now?" He said, "It says something about guns, and that's why I got the call. I'm going to search your car." I replied, "Nope. If you want to go fishing, the river's that way." and pointed in the general direction of my favorite fishing hole. "But it says something about guns." I said, "Are you going to search every car on campus with an NRA sticker, too?" "But son, I'm just trying to do this for your protection. I'm going to search your car now." I told him that if he wanted to protect anything of mine, he could start with my 4th Amendment rights and stop trying to search my vehicle. I also told him if he could give me any probable cause (or even articulable suspicion) for the search, I would gladly open the vehicle, as there was nothing at all in there for him to find. He said, "If there really is nothing for me to find, what do you have to hide?" I told him I had nothing to hide, but he still wasn't searching anything without a warrant. I then demanded to speak to a supervisor if I was going to be detained further. About 20 minutes, the supervisor shows up. I'm leaning on my car, smoking cigarettes and replying to the inquiries every minute or so as to why he can't search (BECAUSE I SAY SO!). The supervisor gets there and asks the officer what the problem is. Officer XXX replies, "He's got a sign that says something about guns, and we got a tip from a concerned citizen. I want to search his vehicle and he won't let me. He's also being a smart little sh!t." I told Sgt. YYY that I have nothing to hide, but no one is searching my vehicle without a warrant. I then asked if I was free to go. The supervisor said, "You sure you don't have anything in that vehicle that we should be concerned about?" I said, "Yes, I'm sure. Am I free to go?" (this is at least the 50th time I've asked this now) He said, "Yes. You might want to take that sign out of your car, though, just so we don't have this problem again." I'm still a little upset about this.
