That's something I don't get either. In a court of law when evidence of someone breaking the law seriously enough to warrant an arrest an officer is called in right then to do it. In this case why wouldn't the FBI have a representative there if asked by congress if they suspect a criminal will be exposed during testimony to arrest the perp right then. At the very least the agent could gather the evidence, take it to their boss, then a warrant issued for the arrest and then they are arrested then get to do the perp walk in front of cameras.
Many in this thread and for a long time now are asking the same question. If we break the law we get arrested and go through the process but when these people commit these crimes, which we consider far worse than garden variety breaking and entering which is what Rice did on steroids, nothing happens and they just get to go on with their life like nothing happened.
In my humble opinion there can be no draining of the swamp, no correcting the corruption, and no fixing the problem with DC until we start seeing arrests and convictions for these crimes. We the people have to know we are all treated equally under the eyes of the law and that simply isn't happening and hasn't been for a long time now. They will continue to break our laws unabated as long as they see no punishment for those who get caught. They have to know they will be looking at a minimum of 5 years in prison and possibly many more if the sentence is based on per count.
What nonsense to believe that any of this can be compared to an ordinary crime, indictment and arrest. Supposition is not enough to convict.
