I was being a little bit glib there. The judge did not literally ask me if I was guilty and I did not literally take the fifth. What she did was ask whether the thing the cop claimed to have seen, which he could not possibly have seen, nonetheless actually happened, and I said I could not remember because it had happened more than a year ago.

It was a very weird situation from a moral point of view because on the one hand, finding me guilty was not supported by the evidence, but on the other hand, letting me get off scot-free would have been even more unjust because the fact of the matter is that I did commit a fairly serious moving violation, and the only reason we were in court at all was that the cop decided to cut be a break and then took a long time to do the paperwork.
