The Trump administration has authorized the use of deadly force for U.S. troops stationed at the nation’s southern border with Mexico, who were deployed by President Donald Trump prior to the arrival of a migrant caravan traveling north from Central America, according to the Military Times.
> The order, which loosens the engagement restrictions on military personnel at the southwest border, was not signed by President Trump, but by White House chief of staff John Kelly.
> It was labeled a "cabinet order," reported the Military Times.
> Under Kelly's order, military personnel at the border are allowed to “perform those military protective activities that the Secretary of Defense determines are reasonably necessary,” according to the report.
Those activities include “a show or use of force (including lethal force, where necessary), crowd control, temporary detention, and cursory search.”
The Hill noted that the authorization of troops engaging in law enforcement activities is likely to invite a court challenge, due to concerns that it violates the 1878 Posse Comitatus Act.
> That law bars active military from engaging in domestic law enforcement, although military force can be used on U.S. soil to "suppress insurrection or to enforce federal authority," according to a report by the Congressional Research Service.
