This seems pretty screwed up if you ask me. My first question is why is a judge using a police roll call room as an impromptu courtroom? Shouldn’t a judge have their own courtroom? Or at least a courtroom shared among several judges?
And if you’re a judge, who has to hold hearings in a police roll call room, isn’t it understandable that the decorum, I don’t know, might more accurately reflect that of a police station rather than a court room, especially one that just lost an officer.
I can understand the desire to create an appearance of impartiality, but when the city apparently has no money for a proper court room, and you have to use a police station, it seems to be you should respect the people who primarily use the room. It’s not like the person appearing before you won’t understand he’s being arraigned in a police station.
