"The officer said he saw the muzzle flashes and felt the glass breaking in his window as the shots came through and struck him in the head,” St. Louis Police Chief Sam Dotson said.

Another Missouri officer was shot in Gladstone, near Kansas City. He’s expected to survive, too.

In Florida, a fourth cop was ambushed. Police believe they have the guy responsible in custody. This officer was making a routine traffic stop when he took a bullet to his shoulder during a drive-by.

The Houston Police Department's official response to the weekend violence against the police is:

“Our thoughts and prayers go out to the law enforcement agencies and the families of the officers who have been either killed or seriously wounded in the line of duty this past weekend.  HPD continues to stress to its officers the need to constantly remain vigilant and aware of their surroundings.  All HPD officers receive training, both as cadets and in subsequent refresher courses, emphasizing threat assessment and situational awareness.  Currently, officers who wish to patrol with a partner may do so at the discretion of their commander.”

Authorities in Texas, Missouri and Florida don't think any of these hits are related. But it makes you wonder while police are protecting the community, who's protecting the police?
