IL Speeding Ticket Question

What is the name of your state? IL
A Tazewell County Cop stoped my brother late Friday night coming out of a friends house. He was ready to give him a speeding ticket for driving our chevy wagon just out of our town too fast. Well he was in school, I was the one that had the car that day. And that is what my younger brother told the Cop. Now the cop still want's to give me the ticket. The Cop claims he got the liecence plate #'s but he obvouisly did not see the driver because he went to my brother first thinking it was him. Can he do this, and he want's me to call him ASAP. Is there things I should or should say, or should I get a some outside help. Also the reason he told my brother he didn't pull the wagon over was because there was a guy in front of it doing the excat same thing and the wagon pulled onto a differnt street before the Cop even was behind the wagon or even had his lights on. So the Cop Followed the other guy and pulled him over instead.

your message was kind of hard to read/undersand..but what I see is the police officer at the very least is confused. IF he did not issue a ticket then, i would not call him back. If he should track you down and start to (write) give you a ticket (at a later date for something you say you didn't do)..look him in the eye and say "..officer If you write this ticket now for something that you say happend days ago.. that I will say it didn't..I am going to contest it in court and ask you to explain why you didn't wite it up the first time? This shows anyone, judge, prosecuter, that at best your confused, and if confused now, were you confused then? Do you really want to go thru this in front of the judge at court?' But be nice about the way you say it to him. He probably will do his 'police thing' and say he is cutting you some slack this time... and both of you move on.
