exactly..
they think they know the law in and out, just like when i gte pulled over and the cop states i clocked you at so and so speed i ask to see the radar and have had a few tell me that they have already cleared there radar off i tell them nicelu have a nice day and i will be on my way, learn that from my ex mother in law ( whose is a cop in louisiana) that if they cant show you where they clocked you then they have no proof that you were speeding.. and therefore cant write you a ticket..
