Update: like many others I was game for waiting in the bush for these scrot bags and ambushing them. I've since come to my senses and abandoned this idea. Too many "what ifs," way too much potential for things to go sideways. These are not kids you can slap around a bit and put a good scare into, they are grown men who have adopted the criminal lifestyle. Good chance they are carrying a weapon(s), even a firearm. It's just not worth getting stabbed or shot. If the police end up getting involved it's not going to end well for the "good guys" who set up an ambush for the bad guys. Yes, it's their word against yours, but what if, say, a dash cam records the whole thing and your story does not match the video evidence. Like I said, too many what ifs and potential for things to go sideways. I can't blame anyone who wants to go cowboy on these scuzz butts, but I won't personally be taking part in a pre-planned thumping.
Now I don't plan to do nothing. I am looking into getting a hidden security camera installed on my truck that will roll tape when my truck is turned off and I'm away fishing. Hopefully it will get a clear picture of a face and/or license plate.
Last few times I've gone fishing I had literally taken everything out of my truck, left all compartments open, and put a sign in the window stating there are no valuables left in the truck. So far I've been good. Yes if is a HUGE pain taking this crap in and out of the vehicle but not as much of a pain as having it stolen + an insurance claim. No guarantee they still wont smash and enter just cuz they can, but i feel pretty confident leaving my truck unattended knowing it has already been gutted and all compartments are open/visible.
