WASHINGTON, USA – Well past midnight one day this spring, three police officers pulled up to a nightclub where a man was stomping on a young woman lying on the sidewalk.

The officers stopped the attack and arrested him, according to a police report. It was the kind of assault police might encounter on almost any night in almost any city.

But one detail stood out to police officer Xavier Jimenez, who wrote the report: “There was approximately 15 national guard members in the area on routine patrol who did not take any action.”

President Donald Trump deployed thousands of National Guard troops to Washington last summer as the centerpiece of what he describes as a no-holds-barred effort to combat crime, especially in cities run by Democrats. Every day, small clots of soldiers in camouflage and body armor patrol tourist-heavy areas of the US capital, including national monuments, subway stations and the area around its professional baseball park.

What the soldiers seldom do, Reuters found, is fight crime.
