Statistics show that since 2000, there have been about 9.5 ambush killings of law enforcement officers per year nationwide, and that the number has been declining in recent years, to about six per year. But this year is off to a horrible start. There have already been five ambush killings in 2016.
There are roughly 59,000 assaults on police officers each year, according to the National Law Enforcement Officers Memorial Fund, resulting in more than 15,000 injuries. Statistics show that about 50 officers a year are killed in criminal incidents, excluding car wrecks and other causes of line-of-duty deaths, the Washington Post reports.
