You’re not really required by law to ‘pay attention’ unless you’re being asked a direct question. Though, I’m sure judges look poorly on such things.

I remember Harvey Weinstein doing the same thing before he got sent to Rikers. :)

Not if you are not required to participate in that part and not causing a disturbance in the court.

This is a jury trial, and jurors are watching. Even during selection. If you don’t care enough to stay awake, it’s not a good impression.

Probably wouldn’t fly. This happens more than you’d think. Court room procedures aren’t as riveting as tv would lead us to believe.

I’ve heard of jurors getting in trouble for it before, but not defendants.
