The Department of Homeland Security on Tuesday reported a 45 percent increase in the number of assaults against its Customs and Border Protection officers from fiscal year 2016 to FY 2017.

CBP recorded 847 assaults against its officers in the just-finished fiscal year, compared to 585 in the previous year, government data said.

Despite the significant uptake in assaults, law enforcement officers are responding less frequently with lethal force, pursuant to instructions from CBP last year.

The year before, officers used firearms in 26 cases and less-lethal means of force in 947 cases. Firearms were used just 17 times in FY 2017.
