I would claim that it would be much more extensive than just a defined answer ; because it can be subjective - you do the crime you do the time .

I guess my answer would be anything that would be considered to break a rule meant to be in place for any reason .
Even if it is intentional or not ; crime can be done accidental .

Perhaps a social experiment is needed ?
Maybe set up an obvious home made sign place it somewhere with a rule and see how many people break this rule ; like no laughing or smiling or fun of any kind . one that would be hard to break - then another sign ; almost professional made with a rule that would be much easier to break ; like keep off the grass

Then try to get other peoples opinion on the matter while trying different methods .
Just thinking " out loud " if you do manage to get to this - i would love to see it ; make sure you tag me in it !
