@tjmcintyre @cstross Primus; you don’t need to subpoena a cop to show up at traffic court, because attendance at traffic court means the cop gets to hang around indoors chatting with their cop buddies all morning & there is nothing a cop likes better. They’ll be there.

Secundus, unless you have actual solid cast-iron proof that you didn’t commit the offense, then the judge is going to listen to the cop. And if you have actual solid cast-iron proof, you don’t need HAL9000 whispering in your ear.
