>why Hillary and Obama weren't arrested.
44 will not be arrested, undoing 8 years of the federal government would relinquish to much power and set precedent for political payback for every president going forward
HRC can be arrested, but to arrest her, you will have to arrest lots of the worlds political leaders
I think neither will be arrested, just lower level actors who names are on documents and easily prosecuted with their testimony redacted for national security reasons so as to not expose those they are not going to prosecute
otherwise you have to go back to 1871 and start the US government anew, rolling back all the laws and amendments that never had a true quorum met
