Hey Everyone.
I was hoping the lawyer types could give me some advice on dealing with the D.A. for traffic court. I seldom get tickets and when I do I normally just pay them (I'm honest enough to take my lumps when caught ). This time I'm not guilty

.
The quick details are:
I was driving my Jetta in the center lane
maybe 65mph in a 55 zone (with traffic), I passed the off ramp before mine and moved to the right lane noticing a black car in it but back a bit (an easy 10+ car lengths so safe to move over for sure). Before I even passed under the bridge the black car is 5' off my bumper trying to push me (I hate tailgaters). Just as I was about to check my brakes he jumps in to the center lane and I see the squad just coming off the on ramp.
With no where else to go I hit the emergency lane so he could pass but no, he pulls me over.
Now the B.S. starts. He claims (verbal) that he had me doing 83 in the right lane

, I tried to argue "no way I was going that fast" but he just took my lic and wrote the ticket. When he returned I (nicely) suggested he had clocked the blk car that was tailing me; I could see it in his face as he looked back at the lanes *oh crap, he's right* but he just said " to late anyway the tickets been written"
Now I have to go and try to fight it because I will not pay for someone else's ticket.
Problem is I figure I'm already found guilty just because he's a cop and the Judge/DA will believe him over me, even with out evidence but I have to try.
Thanks in advance.
