moral of the story dont move soemthing that isnt yours, if they cause problems for " parking" and leaving the keys in the ign. thats their problem, park and walk your happy ass like everyone else.
a mother parks her car to run into a conveniant store for a short time and leaves the keys in to keep the ac/heater on rather than take her child out of the car seat lug the kid inside 4 feet to get a drink and some chips or something for the child
man comes by sees the car running and takes off.... how is that less wrong than busting a window jimmying the lock etc?
getting in a car that isnt your without consent to drive it is stealing.
entrapment is when the law gives you no other choice ( or pushes the odds of you commiting a crime to crimes favor ) but to commit a crime and then bust you for it, ive never seen the show but im assuming nobody put a gun to their heads and fail to see this as entrapment, same could be said if they put a viper on the street locked the doors and set the alarm and watched it, the car was just to damn expensive to pass up.
as far as a 20, i find one i keep it, simple fact is, how many people wouldnt claim found money, even if it werent theirs.
way i see it, if you dont notice you lost it you apparently have plenty to lose and wont suffer at the loss ( not hard to keep track of a few bills )
