Naw, if you abandon something, it’s assumed it’s free game, and the other is done with it.
That depends if I wanted to be excused to go home or not 
Could definitely use it as an excuse to get one or both sides to want to get rid of me…but honestly I would love to sit through trials.
Most likely I would respond:
“I can’t answer that question yes or no without first having been presented with the evidence on both sides.”
