Unfortunately in NC we have a problem with DA's not seeking the death penalty in very worthy cases.

I mean if a person with criminal history commits cold blooded murder in the worst way, on camera with multiple witnesses, then gets in a shootout with police, they should get the death penalty right?

Based on witness statements and store security camera footage, police said a man with a shirt pulled up over his face brandished a handgun and demanded money from Mahmood. Mahmood placed the cash drawer from the register on the counter and put his hands up, and the robber went behind the counter and shot Mahmood three times, including once after he had collapsed on the floor, before grabbing the money and some cigarettes and leaving.

After dropping the money and cigarettes in his car, the robber is seen on security video returning to grab more cigarettes, shoot Mahmood a fourth time, fire shots at the security cameras and threaten customers.

Police officers responding to 911 calls from customers in the store confronted the robber as he left the second time. Officers exchanged gunfire with the man, who was wounded and taken into custody.

The reason DA's dont use the death penalty in certain cases...
