DO NOT run a red light in front of a cop in DC. I'm just putting that out there as kindly intended advice. If you go to DC thinking it's free reign, you're likely to be disagreeably surprised. Especially if you're in the parts of the city that I'd imagine most of the people on HN would be likely to be in.
And Heaven help you if, well, other agencies watching DC misinterpret your red light running. You may be in the wrong place at the wrong time and find yourself trying to explain that to people who, as a general rule, don't believe in coincidence.
Yeah. Just don't draw that kind of attention to yourself in DC. That leads nowhere good.
