In doing that (sharpeing the star so it will cut the heck outta some lowlife star theif), keep in mind it leaves you open for all sorts of tremendous law suits. While I myself would like to have a trunk monkey that would jump out and just beat the hell out of anyone who even touched it, a person has to remember that in our current law system, you could lose your ass by doing something like that. Also, always keep in mind the innocent pedestrian that stupidly stumbles into your car. Yeah yeah, I agree, they should be more careful.... BUT... I'd hate to see some curious little blond haired blue eyed toddler grab ahold of it in one of their known moments of curiosity.
Go out and buy a fog horn, and rig that thing up right under the grille. Scare the hell out of em, but I suggest you don't do anything that would be intentionally harmful........
