Hehe, this one was okay. I kind of like the original joke a bit better cause the ending gives the whole part about the cop calling the chief and telling him everything he heard some logic where as in this one the cop is just made to be an idiot that just says "it will never happen again", like what will never happen again? He won't report to his chief if someone tells him he has a gun on him? xP
and ending with "hehe, because of this they didn't care to look for the 2 kg of weed under my seat" would've maybe given it a bit more wit, where as here he just wastes everyone's time to make the cop feel like shit, lol.
