My question involves criminal law for the state of: IL
Unfortunately this pass week I got charged with almost everything possible. Got charged with 2 Class 3 Unlawful Delivery, Class 2 unlawful delivery, DUI, Reckless Driving, Improper Useage of lanes, Loud exhaust. Some traffic, Some Criminal. Well There were four people in the car, including me, a friend, And my GF and her friend. Well Got pulled over because someone has stated that I was driving all over three lanes(have a 3 lane overpass in town) and went on the curb and kept driving. No cops saw this. Just the person who called it in. Went to go get food. And pulled out of Fast food place, And sorta power slide while leaving the fast food place onto the main road. The Cop said I was Doing "Doughnuts" In the middle of the parking lot. And Did a burnout and Power slide onto the main road. Which I didn't do either but just the power slide. I wasn't Weaving in and out of the lanes. He pulled me over in less than a football field away. So I didn't really have time to weave in and out. But Cop pulled me over and stated all of this I declined that I didn't and didn't like me from there on out. I admit that yes I accept that I got a DUI. But the girls unforuntley were kinda messed/incoherent during this time. When they did a field sobriety test on me. They asked if i had anything on me or in the car. A k9 was there during this time. So i told thme i had weed and a pipe. So they started searching my car. And ask the girls to get out. And started searching them and there belongings. Without really asking for consent. They found 1 Xanax on each girl. And one percoset. So they asked Where they got it from. And one of girls said they got it from me. Then immediately i was charged with the Unlawful delivery. We all went to jail besides my friend. Nothing was found on him. But the girls had no reelection of anything. They remembered one thing at the house and woke up in jail. A pretty shitty way to wake up.

My Questions are:

Can the girls change there statement that they got it from me, I have facebook messages from one of the girls asking if i wanted any of the xanax. Could facebook messages be used in the court of law?

The guy who called me in is the only one that claimed that i was all over the lanes. Could i be charged with the Improper usage of lanes. And reckless driving?

I dont have proof that the girl got the percoset from somebody else. So would it be a he say she say? Even tho she is wanting to change her statement?

I might have more questions but cant think of any of the moment. Thank you
