It’s kind of hard to explain what is happening in the city of Philadelphia today.

Incredibly, mind-numbingly, they are mourning the loss of still another police officer.

Sgt. Timothy Simpson, 46, a 20-year veteran of the force, was killed when his police cruiser collided with another vehicle at an intersection during a pursuit involving a suspected DUI driver.

Simpson is the fifth Philadelphia police officer to die in the line of duty in just the past year.

He leaves behind a wife and three children. And a police force and city once again wearing its heart on its sleeve.

If you see a police officer today, no matter where, why not offer a simple thank you for the job they do every day.
