Officials in Philadelphia are praising city law enforcement for peacefully resolving a chaotic episode Wednesday night in which a gunman armed with an AR-15 and a handgun fired off more than 100 rounds, hitting six police officers, then barricaded himself inside a residence, creating a more than seven-hour standoff.
The suspect is now in custody and all six wounded officers have been released from local hospitals.
