First off: how do you not know the difference between a prosecutor and a judge? Their titles explain what they do....if you can't figure it out then google. Double-check the speed limit where you passed them, take pictures. It's possible you were in a 35 and they wrote a different street name down with a lower limit. Next time don't open the door at all. Cops have to get YOU on the bike, not a guy in an apartment with a bike matching the description in the lot. Even then, you don't have to open the door for them without a warrant. Don't you know your fucking rights? Get your ducks in a row, get docs that prove valid insurance on date of incident, go to court fully prepared to get piped in the turdcutter anyway.
