Report: Gunman Kills Three Pittsburgh Police; Recently Laid Off and Expecting Obama to Ban Guns

The Associated Press reports:

A gunman wearing a bulletproof vest and "lying in wait" opened fire on officers responding to a domestic disturbance call Saturday, killing three of them and turning a quiet Pittsburgh street into a battlefield, police said.

Police Chief Nate Harper said the motive for the shooting isn't clear, but friends said the gunman recently had been upset about losing his job and feared the Obama administration was poised to ban guns.

Richard Poplawski, 23, met officers at the doorway and shot two of them in the head immediately, Harper said. An officer who tried to help the two also was killed.

Poplawski, armed with an assault rifle and two other guns, then held police at bay for four hours as the fallen officers were left bleeding nearby, their colleagues unable to reach them, according to police and witnesses. More than 100 rounds were fired by the SWAT teams and Poplawski, Harper said.

Poplawski feared "the Obama gun ban that's on the way" and "didn't like our rights being infringed upon," said Edward Perkovic, his best friend.

Perkovic, 22, said he got a call at work from him in which he said, "Eddie, I am going to die today. ... Tell your family I love them and I love you."

Perkovic said: "I heard gunshots and he hung up. ... He sounded like he was in pain, like he got shot."

Poplawski had once tried to join the Marines, but was kicked out of boot camp after throwing a food tray at a drill sergeant, Perkovic said.

Another longtime friend, Aaron Vire, said Poplawski feared that President Barack Obama was going to take away his rights, though he said he "wasn't violently against Obama."

Obama has said he respects Americans' constitutional right to bear arms, but that he favors "common sense" gun laws. Gun rights advocates interpret that as meaning he would approve of curbs on ownership of assault and concealed weapons.
