I’ve heard of a new product that triggers a smoke bomb so that the scum can’t see what they are doing - you just don’t want to forget about it if you are late for work one morning
How about rigging up a couple of sawn off shotguns to a trip wire so when someone tries to get in the garage without permission they get there head removed along with various other body parts!
Plus that way when you argue with the wife just send her in the garage
I have been looking at using the device that you have out a link too. But the problem then is that the thieving scum will see that there is something in there…
Remember that film Flash Gordon (not Flesh Gordon!) when he fights Tim Dalton on the spikey floor, that would be quiet good to harpoon the burberry chav b’stards on the way out. Bleed you chav scum!!!
