If your kid was busted for Graffiti walls and land marks there a better way to tech them a lesson that would

(1) embarrass them
(2) Teach them a lesson
(3) Respect other peoples property

first confront your kid and ask about it and why he did it
then if he cant answer it take all his clothes put them all in the washer and use bleach and beach the colors out and dry them and put them away.

Make him wear them for awhile this way he gets the point not to do it again that way he learned a lesson .
