It seems the rules are different for me than for you. I brought my backpack with my laptop. I did work during breaks. Or used my phone. I just made sure all electronics were off when in the court room. And I’m pretty sure I brought my water bottle too. The one thing that the security did enforce was my pepper spray, which I had to remove and hide in a bush outside. I’m not sure if that helps at all.

One thing you can do is to leave your laptop/things in the car. You can leave the building during breaks and then just come back into the building before the session restarts. That was what most of the jury did during breaks during my time
