Consistent with the Attorney General's previously-examined view that the Constitution's definition of treason and its standard of proof are no barrier to intentionally killing Americans with remote-operated vehicles, the President's nominee John Brennan opined during confirmation hearings for the role of Director of Central Intelligence that such killings were completely legal.
In the old days, the fact the Constitution prevented treason convictions without the testimony of two witnesses to the same overt act protected Americans from the risk of persecution on the mere say-so of government officials. And there was always the safety valve of the right to a public trial by a jury, rather than Star Chamber "justice" decided in some high-security venue untrafficked by unauthorized personnel. It might have been inconvenient occasionally, but people were secure they had rights. No longer.
All we need now is to make sure government officials don't believe we're the enemy. We know how to do that, right? I mean, it's not like they're allowed to change their minds ever, are they?
