I don't actually know anything about the particulars of his legal troubles but this assortment of charges looks very much not at all serious and actually is pretty consistent with the every day BS bad policing tactics that plague our system. The likely story there is being pulled over on a motor vehicle stop for a traffic infraction that was then used as a fishing expedition by a power hungry, low-self confidence cop who gets off on being a hardass to people, and it devolved into warrantless search of car (good chance via manipulative , unscrupulous tactics) and the cop threw the book at him just because he could and likes being a bully even when it can ruin someone's life.
