I'm a school bus driver and I regularly get infuriated by people who drive past me when I have my red flashers on and stop sign out, wishing there was a cop around. Only once so far have I gotten my wish ... and unfortunately it was the cop driving past me at 40 mph just as some of my kids were about to cross the road. I looked down and saw him with his phone in his right hand and his left hand on the wheel, not paying the slightest attention to what was in front of him.
I'm lucky he didn't run over any kids, because I probably would have gotten shot.
One of my favorite justiceporn vids was a woman that habitually drove around a stopped schoolbus (on the freaking sidewalk) on her commute. Cop was waiting for her one day and she got roflstomped by the judge on those charges.
I don't want to be the guy defending cops, but there is usually more than one officer in a squad car. There is no rule against a passenger being distracted.
