I had a piece of poo, dead Nissan 4x4 in my drive, circa 1993.  Kids were hitting cars nightly for change, cigs, guns, purses, and elecronics.  At that time my PD had a publication that came (kinda an intel thing) that offered dog shit essence, gas tank gel, and best to of all, an OC grenade, 2 second "full on" empty, trip wire activated, about 12 full ounces IIRC.  It had a vertical dispersion like a fire hose, a base plate, etc.  
Sadly all illegal now.
I might have scattered change and a dead "walkman 2" on the dash, some small change on the console, a pack of marlboros. Parked right at the sidewalk in my drive, facing out.  Under the street light. A true car pirate haul.  Drilled a trip wire hole from under the walkman thru the dash into a Burger king bag on the floorboard that held (barely) the OC grenade and holder which I screwed to the floor aimed upward into the seat compartment.  
I know it worked because there were keys, cigs, money, walkman, sneakers (his) hat, (his) and subsequently a snot rope about ten feet long draped across the sidewalk and lawn.  The door was open and I laughed till I cried.
darn small truck, hard to get out of since it was parked tight in between my two locked cars, and thorny shrubs on both sides.  
Just like trapping a mink.  Make it smell good, make the trail small, make the cubby very interesting, make it very regretful.
I always wanted to charge a magneto, set it up to discharge about 10billion volts when someone grabbed a case of Old Milwaulkie from the seat while standing on a wet car mat.  I wanted to recover smoking sneakers.  
Someday I will reveal in detail  the Stenchonator 2000, used to discourage my stinky ass neighbors who insisted on smoking 10 feet outside my bedroom window, every day, crack of dawn.
A small tube fan, 3 inch PVC pipe and elbows, an extension cord, a rubbermaid bin and lid with construcction glue, an intake, a one way valve, water, dog crap and a dead groundhog....a shed , a woodpile ten feet from their smoking hut, a timer and a few hot summer days.  
After about three weeks, no smokers.  They moved out!  
Never be rude to a snert.
