I realize it seems excessive, but the attorneys aren’t taking long lunches and chatting during those breaks. The midday breaks are for water, bathroom visits, and to deal with any legal issues that came up or are about to come up. Over lunch, as a prosecutor, I have to get escorted back to my office if I have a weapon or a controlled substance. Then I have to call my afternoon witnesses and make sure they know when and where to be. I often have to meet a civilian and walk them to court. But again, I I have to wait for an escort. Then I have to do an A/V test on any recordings/video for the afternoon session. If I get less than 90 minutes for lunch, I’m not eating. I keep protein powder in my office for just that purpose. We do not have the staffing to have assistants or other people do any of that for us unless it is a homicide or there is a victim that got shot/stabbed.
Once court is done for the day at 4:30, I have to contact the next day’s witnesses, ready any exhibits, make sure I have coverage for any cases on the next day that I can’t attend, etc. when you’re on trial, your work day is typically 10+ hours. The “trial diet” is often joked about because you’re all over the place and no time to stop and eat.
