The Mechanical Arm

The mugger tried to take the girl’s purse.
She fought back.
And lost, with a bullet in her heart.
Despite the fact that the girl in the street was dead, her mechanical arm was still running.
The AI routine was cycling through idle behaviors, drumming the fingers on the ground, opening and closing on its own.
She liked to wear gloves, so the lifelike sleeve with the tattoos ended up convincing the mugger that she was still alive, so he shot her a few more times.
The hand kept moving, twitching, and the mugger picked up her purse and ran.
