Off-Duty Shooting on West Side

Starting in 012, ending in 011:

• An off-duty Chicago police officer shot and wounded a gunman after witnessing a shootout that left a bystander injured, authorities said.
  
  The officer saw the exchange of gunfire near the intersection of West Jackson Boulevard and South Leavitt Street around 10:15 p.m., according to Pat Camden, a spokesman for the Fraternal Order of Police. Investigators would later learn one of the bullets struck a man who happened to be nearby.
  
  Four of the people involved in the shootout then jumped into a vehicle, and the off-duty officer began to follow it south on Leavitt, Camden said. Three blocks later, the suspects' vehicle became stopped in traffic at the intersection of South Oakley Street and West Van Buren Boulevard, where an Illinois State Police trooper was conducting a traffic stop, Camden said.
  
  The Chicago police officer approached the vehicle and announced his office, Camden said.
  
  "Two in the back seat are armed," Camden said, retelling the story hours later as he stood steps from where the car had been stopped in the Near West Side neighborhood. "One of the offenders in the back seat raises a .45 [caliber handgun] at the officer."
  
  The officer opened fire, striking one of the occupants, Camden said. The vehicle sped away and the state trooper followed, Camden said.

Car crashes, three escape, wounded offender captured and a gun recovered.

No cops injured and apparently no innocent bystanders in this one. "Exchange of gunfire" meaning a bunch of fools shooting at each other. Nicely done.
