Crap like this has got to stop. And the officer who fired, at the least, (updated)

needs to be looking for a job outside law enforcement.

Asshole, mad about argument, makes fake 'Murder! Hostages!' call to cops.  Cops show up at house.
Officers went to the 1000 block of McCormick, preparing for a hostage situation and they “got into position,” he said.

“A male came to the front door,” Livingston said. “As he came to the front door, one of our officers discharged his weapon.”

Livingston didn’t say if the man, who was 28, had a weapon when he came to the door, or what caused the officer to shoot the man. Police don’t think the man fired at officers, but the incident is still under investigation, he said. The man, who has not been identified by police, died at a local hospital.
If they'd found a weapon, they'd damn well be saying so.  If he'd fired, they'd damn well say so.  From what we know, dumbass fired as soon as this guy answered the door, because... incompetent?  Panicky?  Stupid?  So now an innocent is dead, the department looks like idiots,

The asshole who made the call?  Prosecute him for the heaviest charges possible: he took an action he KNEW could get someone killed, and he needs to pay for it.

Update: they caught the piece of shit responsible for the call.  And have set the defense for the shooting:
...Finch moved a hand toward the area of his waistband...
