Deadly police ambush attacks on the rise in 2016

The deadly shootings of two Des Moines police officers are only a reminder of a year marred by ambush attacks on law enforcement.

In 2016, ambush attacks have become a sad reality and danger for those who serve in uniform on American streets.

The National Law Enforcement Memorial says officer fatalities are up 11 percent, and the fatal shooting of police officers is up nearly 50 percent from this point last year.
