It isn’t, but it happens. All the time in the modern world. And honestly when the whole trial is on TV expecting the jury not to text anybody is kinda silly. And we declared a mistrial every time it happened we’d never finish a trial anymore. Judges tell attorneys about all kinds of stuff, and often to tell them “we’re not having a mistrial, move on”.
So hey, anything goes now. Why even have rules about how to not be a kangaroo court anyway, since all courts are gonna kangaroo anyway, dude.
Dude.
