Okay so he didn’t chase them on foot, which no self-respecting police officer would give a shit about, but he got in his car and tried to Hollywood car chase them and then reality ensued.
Like I feel for him, but he fucked up. He did a damn stupid thing and the only reason any public sentiment is on his side is because he didn’t maim or kill an unrelated party.
EDIT: also as an aside, the police are likely very much on his side, but they’re obligated to charge him with the offences he committed. Any leniency was up to the Crown Prosecution Service, who could have reviewed the facts and returned either a heavily reduced prosecution or even if they were feeling magnanimous (or very drunk), decide he had no case to answer.
