You need to put the hottest chile powder you can find in the vaseline. Then when the perp wipes his eyes or takes a leak...Whoa!!!!

or some kind of deer scent ,skunk scent, something that smells really bad in the vaseline

Chile powder - I also thought of that too. I feel so warm and cozy inside among my brethren.

Are you or do you know an electrical engineer? Shock therapy is in order.

Nah, need to get some scorching Dave’s Ultimate Insanity Sauce for that.

Or better yet get some pure capsaicin. Capsaicin BTW it the chemical compound that makes a Habanero chili pepper hot, and in pure form is rated at 15,000,000 Scoville Units. In comparison, Tabasco Sauce is rated at a puny 2,140 Scoville Units.

Fresh red chillies (the hottest ones you can find). Take the seeds (seeds are the hottest part) and crush and mix with a little bit of vinegar, mix with the hottest Chinese cooking oil, then coat.

Not cheap, but then again when the perp goes to rub eyes, pick nose, or whip out his little..... to take a leak: PRICELESS!
