Not sure how public or new this information is, maybe it has even been brought up on the forum, but my local gun shop made me aware of a method gangs are using for acquiring firearms from drivers who carry concealed weapons and after viewing a center console lockbox install thread I thought I'd try posting about it.
It was observed in Texas and is making it's way around the internet, but essentially the younger gang members carry a paint marker or some form of identifier. When you go into a gun shop they observe if you remove a concealed weapon from your vehicle or if you have a holster in the vehicle. If you do, they dab your tire with the paint. Marks in Texas are usually red about about the size of a marble or dime.
Driver's don't notice because it looks like the mark some tire manufacturers use for valve stem alignment, so it gets dismissed.
When you go to a restaurant or movie and your car is seen with the mark they break into your vehicle and steal the safe or firearm and you're left wondering how they knew it was under the seat, or in the glove box.
For this reason I am installing a safe in my Ram, hopefully this helps you as it did me.
