Are there legal assassins in the US?

In the U.S., there are no legal assassins in the sense of individuals who are authorized to kill for hire. However, certain government agencies, like the military or intelligence services, may engage in targeted killings under specific legal frameworks, typically in the context of national security or combat situations. These actions are governed by laws and regulations, including international law, and are subject to oversight. Civilian killings for hire remain illegal and are classified as murder.
