Australian man gunned down in driveway by killer robot

He spent hours searching the Internet for a way to kill himself, downloaded what he needed and then built a complex machine that would remotely fire a gun.
…
The machine was attached to a .22 semi-automatic pistol loaded with four bullets.

It was able to fire multiple shots into the man\’s head after he activated it.

Doesn\’t that violate one of the 3 Laws?
