POLICE guidelines for stun gun use fail to warn against firing at people in the chest - which has been linked to a fatal heart attack.

The US Federal Court recently found a Taser fired at the chest was responsible for the death of Darryl Turner, 17.

The Greens MP, David Shoebridge, yesterday called on the state government to revise its NSW Police guidelines on Taser use to instruct police against taking aim at the chest.

The current guidelines advise to aim for the back and avoid targeting the head. Otherwise, they should aim for the lower torso, avoiding the face or groin.

However, nothing in the guidelines instruct police officers to avoid the chest area.
