Addressing the BS theory of Obama wanting to declare martial law.

There is no conspiracy to deflect media attention from Hillary Clinton or for the president to declare martial law to stop the upcoming election to take over the world.
Let us look at things logically

To orchestrate a shooting to ignite racial tensions you would of course need a shooter or a willing victim to provoke a shooting.

Shooter- the conspirators would need to find a person willing to risk being a sacrificial goat. You would need to look around for a willing shooter it is not like they advertise "Police Officer willing to shoot black people to facilitate starting a race war in order to declare martial law." And I don't think you could just call around looking for a cop that would do it. And you can't plant a person in a department to do it.

The victim- not going to get too many volunteers for this side. Can't advertise for "black man willing to provoke cop to shoot you dead without making it look like you did." The victims history shows this to be highly unlikely.

The numbers- to orchestrate such a plan would require many people and it has been proven the more people privy to secret the more likely that secret is revealed. As people are added to the secret the chances of exposure goes up and the chance of success go down. You increase chance of failure because you add more parts that can fail. It is that simple.

The President is bound by law and though he can suspend certain things because of emergency the Constitution cannot be suspended in itself. The right to a Writ of Habeas Corpus has been suspended by presidents during Wartime for security reasons but not much more than this. President Lincoln did so during the civil war and I think Franklin D. Roosevelt did so for WWII. The Civil War was the most divided this country has ever been yet the presidential election still went on because it says so in the constitution and even presidential authority cannot supersede that. During WWII the presidential election still took place.
The key here is what gives the president his authority and that is the constitution. The president cannot suspend the instrument that gives him power. If he were to try he would fail because it is against the law and he cannot order the military to impose martial law that keeps him president and suspends the constitution because that is an unlawful order. While the military is required to obey those officers appointed over them the do not have to obey an unlawful order even from the president.

Our system is set up in such a way that no one person or person can circumvent the constitution. Checks and balances limit the power of each branch of government. If President tries to take total control and suspend the constitution it would be considered unlawful and congress would impeach them. If congress tried to pass laws to suspend constitutional rights the president can veto the law or the Supreme Court can overturn the law. The Supreme Court can decide the constitution legality of laws but they cannot make laws. The Supreme Court can, and has done so in the past, determine if the president has exceeded his constitutional authority. All these ensure no person can become a dictator in the U.S. The movies tend to exaggerate what the president can and cannot do.

Unlike other countries our elections are fixed by law and cannot be changed nor suspended.

The sad truth is this conspiracy theory is spread by a think that was designed to facilitate the spread of knowledge. The theory holds no water when compared to "true facts" and logic. It is a ploy by people who want to pray on fear to get people to come to their side which is based on ignorance.
