Over the course of the weekend a beloved Philadelphia Police Officer was shot and killed as well as five other people in the course of a few hours. Despite video footage only one person has been arrested. Police search for Officer Moses Walker Jr.'s murderers and a rising reward of $118,000 hasn't brought a tip. Officer Walker finished his shift at 6:00AM. A co-worker offered him a ride home, but he decided to walk as it was a nice morning. He changed into street clothes and went to enjoy the finally somewhat cooler morning, and was murdered in cold blood. All the cameras in the world and this Officer and five other citizens are murdered in cold blood. http://www.philly.com/philly/news/2...led_over_weekend__but_just_1_arrest_made.html RIP Officer Walker. I am so sorry you couldn't just walk home or to a bus stop without being murdered.
