Someone do a group buy for recorders..
So basically once you get pulled over, turn it on, and it shall record all conversations.. So you have proof that you arent swearing or having a go etc etc..
But seriously man, go speak to someone higher in charge and explain the situation. Tell them, the cop wasnt poilte in anyway.. Hassle them till they drop the defect charges.
Go after it man.. Dont sit back and pay the fines!!
