The attacks highlight the growing dangers officers are facing across the country. According to the National Law Enforcement Memorial, fatal shootings of police officers are up by almost 50 percent from last year. 

Counting Wednesday's attacks, there have reportedly been at least 16 deadly ambushes so far this year. 

Law enforcement experts consider an ambush a sudden attack from a concealed position, with the officer not having provoked any attack.
