I am curious about this reckless driving charge. He came in with relatives to the station in a car, not his car, since LE has his car, do they not. When he leaves, he's driving someone else's car? I can' t imagine anyone who knows him well , that would accompany him to the police station, to be his moral support would trust him driving the car that is not his, given the condition he keeps his car and his running list of traffic and car probelms. Plus, they would have to know he is distressed and in trouble over all of this. YOu'd let someone like that and in this situation drive, and drive YOUR Car? Not going to look good for LE , if indeed they cannot prove he was the driver.
But yes, this is what LE does a lot. Try to lock up suspect for something serious on minor charges and get him in their sights, try to get him to talk, stick him in a cell with an informer. That's pretty standard. Also, they know that it could be a problem locating the person if needed later, as one can see from this--The lawyer probably told JM to make himself scarce.
