Already this year, eight on-duty police officers have been killed by gunfire — including five this week alone.
The 2016 gunfire fatalities mark a notable increase from the same Jan. 1 through Feb. 11 period last year, when just one officer was shot dead, according to theNational Law Enforcement Officers Memorial Fund.
In total, 11 officers have died this year, versus 13 officers in the same time frame last year. But most of the deaths last year were traffic-related, not firearms-related like they are this year, according to the National Law Enforcement Officers Memorial Fund's tally.
