Roberts has already committed treason by arguing for the rule of the mob over accepting the valid electoral fraud cases brought before the SCOTUS. Refusing to hear these cases amounts to conspiring to give aid and comfort to the enemies of the US. That is clear.

That said, once the oath of office is given to him a president elect becomes president and it is almost impossible to arrest him. He would have to be impeached and that has to happen in the house, which is very unlikely.

Therefore, sealed indictments are ready to be unsealed and arrests are going to happen before inauguration.

It's pretty clear that's what the heavy NG presence is for - to prevent a major riot when the arrests happen.

Frenly reminder: the 19th is National Popcorn Day.
