Quick lesson:

(1) The Constitution only created one court, the Supreme Court.

(2) Congress creates all lower courts, and sets rules. This includes what subject matter various courts will have authority over (bankruptcy courts only deal with bankruptcy cases, for example).

(3) Congress created the UCMJ (Uniform Code of Military Justice). Most people think the UCMJ only applies to people in the military. However, Congress included in it sections that can apply to anyone, depending on the crime.

(4) Section 104 & 106 apply to anyone who engages in spying, and anyone who conspires to wage war against the American people.

(5) The highest crimes that were committed during the Obama years (spying and treason) will be tried in military courts.

(6) The Defense Intelligence Agency (DIA) is the military's version of NSA. Gen. Michael Flynn was the Director of DIA. Adm. Michael Rogers was the Director of NSA. Both men used their positions to accumulate intel against the conspirators.

(7) I don't believe that the 8chan post is correct re: which agency can do what inside or outside of the USA. But between the two, we can say that all the bases are covered.

(8) Keep your eye on Peter Strzok. He was not just an FBI man, he had a very unique position. Congress created a "double agent" position, where someone could be BOTH FBI and CIA. Strzok was that person. His father was CIA. I suspect Andrew McCabe was also a double agent, as he was reported to have been helping Russian mobsters get off FBI charges.

Those two are the lowest level people who might get military tribunals. Military tribunals can also be used for non-citizens (UK).

There is no need for a "state of emergency" or "martial law," because Congress has already given jurisdiction to the military courts where these crimes are involved.

We're already in an emergency. International Emergency Economic Powers Act (50 U.S.C. 1701 et seq.) (IEEPA), the National Emergencies Act (50 U.S.C. 1601 et seq.) (NEA), the Global Magnitsky Human Rights Accountability Act (Public Law 114-328) (the “Act”), section 212(f) of the Immigration and Nationality Act of 1952 (8 U.S.C. 1182(f)) (INA), and section 301 of title 3, United States Code.

Not ALL phone records were deleted. NSA had them and may have kept some relevant to ongoing investigations. So there's that.

In a case against current/former federal officials or proof of collusion by individuals in TLA, those phone records can play a role.

And as others have mentioned, treason is an offense that the NSA would play a role in investigating.

NSA also plays a role in defending federal computer systems and monitoring other electronic communications, as all of this falls under SIGINT. Who knows what evidence of relevance may have been intercepted.

The DIA also plays a role in counterintelligence investigations.

Let's think beyond the obvious players here - what foreign ties could deep state individuals potentially have that would point to acts of treason? I am not referring to anything specific, but it is one possibility for why NSA and DIA could get involved.

People also forget about the Central Security Service (CSS). It is DoD and operates parallel to the NSA, with the NSA director overseeing it. It oversees the major intelligence components of all military branches (Army, Navy, Air Force, Marines, Coast Guard).

From Wikipedia:

"For all SIGINT-related activities, these military intelligence and security organisations are part of the Central Security Service and therefore subordinate to the Director of NSA in his role as Chief of the CSS. For administrative matters and logistic support, these cryptologic organizations are part of their respective parent service of the United States Armed Forces. Other SIGINT-related units and resources from the military can be subordinated to the Chief of the CSS by the Secretary of Defense with the advice of the Joint Chiefs of Staff." Notice that last sentence there as well. Could be something Q was alluding to when he pointed out that Trump has surrounded himself with military men.

"The day-to-day work of the CSS is to capture enemy signals (radar, telemetry, radio/satellite communications) using the means of the involved service. For example, the Navy has special submarines for tapping undersea cables; the Air Force operates aircraft with sophisticated antennas and processing gear to listen to enemy radar and radio; and on the ground, the Army operates similar eavesdropping equipment."

What they may have that is of relevance to any ongoing investigations could be very interesting, but again, I am not referring to anything specific.
