That was an FBI show for intimidation. It is a common mafia tactic, of showing force to the point of no return, and then backing off. It is designed to send a message that next time, we will break a leg or worse. The leg break was the Kangaroo Courts in Georgia and NYC. In a figurative sense Trump is being hobbled by the Biden mafia, unable to campaign as much.
What is coming up is the Hunter Biden days in Court; June. The Mafia intimidation of witnesses is no longer working. It appears Trump is beating the kangaroo courts and new witnesses for the Prosecution are coming forward. The writing is on the walls. It looks like Trump will become President and any witnesses forced to stay silent, are coming forward. They wish to leave the sinking ship; witness protection, rather than go down with that ship. This will position them better in the future.
