Jesus...

What is wrong with you people. He hardly even threatened your mother... Don't try win a battle so petty with a cop, you will come out second best.

You guys haven't seen police brutality...

Just let it slide, it's not worth the effort. What will this cop do anyways? NOTHING, because if he does get legal with you, he has no ground to stand on. Just leave it, keep on toking and peace out. You don't need to apologize, just leave it... Be the more mature person, and don't retaliate like a kid, look at where that got you in the first place.
