WHy do you seem surprised by this? Do you know how many times John Gotti got indicted before they finally were able to jail him?
Major crime family figures with good lawyers can both game the system and stretch things out a long time before the system eventually gets them.
But just as we should all be glad the system persevered to get Gotti, so to should we expect it will to get Trump. We are watching his crime spree in this term in real time and the next Dem gov't and Potus and AG better assign 3-4 Special Prosecutors to track down each and every avenue and with speed as we do not want Trump dying before they are done and all the cases then dropped as we need jury verdicts, either way, on them all to close this chapter.
