From Nikita Vladimirov writing at The Hill:

Ambush-style killings of police have increased by a staggering 300 percent since last year, according to the National Law Enforcement Officers Memorial Fund (NLEOMF).

“Firearms-related fatalities (32) spiked 78 percent in the first half of this year from 18 during the same period last year. Of particular concern, ambush-style killings of law enforcement officers have dramatically increased more than 300 percent from the same period in 2015,” said a report from the group.

“Fourteen officers were shot and killed in ambushes, seven officers were killed stopping a suspicious person and five officers were killed while executing a tactical arrest or high-risk warrants” it added.
