What are the implications of the govt's plans to beef up citizen arrest laws?

Destiny Church leader Brian Tamaki has expressed his enthusiasm for plans to beef up citizens arrest laws. Some Destiny Church supporters are currently being investigated by police after they stormed a children book reading that was part of Pride week celebrations. The government's planned amendments to the crimes act will mean citizens can detain and arrest someone suspected of a variety of crimes including shoplifting and more serious things like child abuse. Barrister Henry Benson-Hope spoke to Lisa Owen.
