No, I'm saying smoking weed and causing and accident is less of an intent (being weed it's far less than any other drug, btw) than a fighter willingfully hit someone in the face. Criminal intent is a major factor, people without it are not exactly criminals, just reckless or stupid, Jones is both.
Video shows that McGregor had full intent to hurt an old man, that's utter proof, we can argue that he did not KO the old guy, but had that guy fell from his stood and end up breaking his bowl, from there onwards his life would be over.
Jones was doing the right thing driving high and accidentally hitting a poor lady? No, but then we don't know what happened there.
There's no video, there are dozens of things that might have happened to ease up Jones case as well, did that woman see Jones? Were she jaywalking at the time? Was it the in a middle of a road or right after a turn? List goes on..
