1/ Indicting a former President is going to have some interesting repercussions. It represents a major sea change in how this country works, if indeed it does work.
You have to understand how these people think...
They don't believe people get arrested for breaking the law. They believe people get arrested because they have no power.
The only reason Presidents and Senators etc... don't go to jail all the time, is because everyone on both sides agrees not to use their power that way.
