The Constitution doesn't require judicial process. It requires due process. Warmaking and national defense powers lie with the executive and legislative branches, and there is precedent that the courts should not interfere with the military chain of command. The executive informed the congressional oversight committees more than a year before the assassination. Spying on Americans without a court order is illegal. The US government can still spy on Americans with a warrant.
