unless you`re a witness summoned to court i don't think you have to answer questions even as the defendant.
I'm not an expert in law, either side of the border but I think it's all or nothing. If you take the stand in your own defense you can be cross examined. I'm sure you can't be forced to testify against your self.
I don't know about grand juries and if they have more power. Can DT be forced to testify against his cronies? Loyalty isn't his middle name. Then do they blab likewise?
The antics could eliminate the need for soap opera writers. What isn't in the plot? We've got sex, violence, insurrection, fraud, politics, revolution, finances, riots, civil rights, ecology, brain washing, all smothered with a layer of Coronavirus ketchup.
I don't know if we'll be laughing or crying. Maybe it'll be like a night at the bar, everyone having a good laugh until they see the tab.
