Lance Burdett - Police negotiation

This week's siege of a house near Kawerau where four police officers were shot has highlighted the importance of negotiation. The alleged offender gave himself up without a fight after an overnight standoff with armed police and defence force personnel. Lance Burdett is the New Zealand Director of the International Association of Hostage Negotiators and spent 22 years with the police - much of it training 111 staff to deal with violent or suicidal callers.
