How many alleged DUCO violations do you think there are? I'm only saying that he was driving under the influence and thus not falsely arrested. "I have a crappy car and thank you for saving my life" as a jury nullification defense doesn't seem to far fetched or not worth prosecuting as a DA. I'm not seeing this as a critical law enforcement issue that needs additional legislation. Having a crappy car and have a CO detector may not be a bad idea on a personal level. If this were an actual problem however I think we'd see the left as having been calling for CO detector mandates by now.
Oops, I just spoke it into existence.
