>> Was he not a self proclaimed leader of the Al Qaeda organization? How is he not an enemy combatant?<<

He was a US citizen was he not? Does the constitution give rights to US citizens or does it not? Who declares someone and “enemy combatant? Are you an “enemy combatant because you want to overthrow the current leaders in the US?

Does the constitution give rights to US citizens or does it not?

No it doesn’t. The Constitution clearly states they are rights bestowed on us by our creator. You ought to get someone to read it to you sometime

You are an enemy combatant if you lead military forces against the people and government of this nation for the purpose of killing and destroying, particularly if those forces are sworn enemies of our government and our government has designated them enemies of the state to be hunted down and destroyed wherever they are found. Nor are we alone in this. Many states such as Yemen, the government responsible for the killing in question, have similarly sworn to destroy the leadership and facilities of this nefarious organization.
You miss the delicate point that citizenship rights extend only so far as citizenship is acceded to. Once a putative citizen becomes an enemy of the state and takes up arms against the state they have forsaken their rights as citizen.
Birthright citizenship does not confer absolute protection of Constitutional rights. If the individual has rejected Constitutional authority in their words and deeds and has joined an enemy sworn to the destruction of Constitutional government they are by definition an enemy combatant and are fair game for the military when charged with their destruction.
In war the niceties of law and judicial review are effectively suspended. There may be instances where trials are appropriate. Enemies on the field of battle are not among them.
