Under provisions of both the Homeland Security Act, Military Commissions Act(s), and The PATRIOT Act, the POTUS, either via his sec, or by sending armed troops to halt the attempts to resist launched by pseudo state operative Elaine Duke, current Secretary of Homeland Security, may engage in any number of activities to halt treason by forces hostile to the United States within the Armed Forces, or cease an entire Dept of US Gov from its compromised authority. These were checks and balances to the usurption and abuse of US internal policy which, as in the case of some Sept 11 Attackers whose visas were not thoroughly vetted, where these bureacratic practices could amount to "holes" in the US statuatory armor. Also, the Pat Act gives Potus the authority to declare any group hostile to US "terrorists".

At that point, under PATRIOT Act detention is legal, and under the Military Commissions Act of 2008, the tribunals are now engageable.
SUMMARY
MI does not answer to Congress, has the most access to mined data and classified information. They have the best information gathering tools. They also have more power in general and are devoted to the constitution. MI can take over the investigations for the other three in cases of high treason. The State Secrets Act was upheld in the Supreme Court United States v. Reynolds, 345 U.S. 1 (1953) acknowledging the right of the government to exclude evidence in a trial that may harm National Security. The President is the Commander in Chief of the Military and the Chief of Staff is Gen. John Kelly, a Marine. The President can use military (& National Guard) as police force in the event of terrorist act, natural disasters and disorder that state police cannot contain.
