Death raises concern at police tactics

The recent killing of an unarmed Virginia doctor has raised concerns about what some say is an explosion in the use of military-style police Swat teams in the United States.

Armed with assault rifles, stun grenades - even armoured personnel carriers - units once used only in highly volatile situations are increasingly being deployed on more routine police missions.

Dr Salvatore Culosi Jr had come out of his townhouse to meet an undercover policeman when he was shot through the chest by a Special Weapons and Tactics force.
