My question involves criminal law for the state of: Illinois
I was on I-80 going in between my town to another town about 20 miles away. While on the highway there was a couple that was tailing me for most of the way, even while going well over the speed limit. i was passing people and there were other cars in front of me and when i slowed down to 70 while passing a truck she flipped me off several times. so i smiled and waved and tried to speed away from her. She comes back trying to pass me on the right side even though i was about to pass people while in the left lane. etc etc, she flips me off more and a similiar pattern continues until i get to my destination.
i get off the exit and i notice the car is still behind me. so I get a little worried that this person is upset enough to follow me. While driving in the town's main road we come to a stop light and the passenger jumps out, slams his door and appeared to be running towards my vehicle. So i quickly jump into the right turning lane onto a less busy street, do a u-turn and go back to the same intersection on their right side. They pass me when their light turns green. she makes more innappropriate gestures at me and I again smile and wave. i get back onto the main road and now i'm a few cars behind them. they end up going the same route i take when i go to my church. at a right turn only they turn left and begin to turn around, where i stared at them, shook my head while holding my hand up to my neck that they mistook for a slicing motion across my neck.
me and other friends take that same route while going to taco bell. cops are there and she points me out while in my friend's vehicle.
they pull us over and arrest me. they didn't read me my rights, though from what i understand they didn't have to.
i need to know what I can do. they had no right accusing me of disorderly conduct as they were doing simliar things during the entire highway scene and also came running toward my vehicle that made me feel very uneasy.
