This isn’t about Islamic terrorists; it’s about being able to disagree with our government without being snuffed.
I agree with goldstategop and Ambassador John Bolden. The Constitution says that the President is the CinC of the Armed Forces of the US. IOW, it is his responsibility to protect the USA.
If, on any president’s watch, a situation arises in which a US citizen poses an imminent threat to the citizens of the US, then at the president’s discretion that threat can be taken out or captured. It is all situation dependent.
If we read the US Constitution, we find it listing no exceptions under the CinC authority of the President. The preamble clearly spells out that one purpose of the US Constitution is to provide for the common defense. Immediate defense needs in crisis situations are not provided for in declarations of war, in reprisals, or in covert operations.
Therefore, any restrictions on the authority of the President to counteract imminent danger must have been duly passed as legislation by both the House and Senate and signed by the President.
