Tucker is 100% at fault and in the wrong, but the report was that he slowly went past a STOP sign, not that he was speeding. Of course him driving in any fashion is wrong, but it's difficult to injure anybody when going as slow as Tucker was, or may have, been going ... Maybe he was driving a few blocks to get to the nearest public transportation, knowing that he couldn't drive in his condition?
There is definitely an amount of respect lost toward PJ Tucker from this incident, but the "amount of respect lost" is still up in the air depending on the circumstances of the situation.
