“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.

This seems quite unusual. Looking at details, Wichita KS has a population of 380K. Perhaps they don't see much of hostage situation and were ill prepared for it. Would be interesting to see the results of investigation. Also there were studies that looked at how stress could result in these kind of scenario. IIRC, one of the triggers were being on a suicide watch/dispatch call.
