Hutt City Council parking wardens are the latest in a long line of frontline staff to wear lapel cameras to deter assaults and verbal abuse. These lapel cameras are another illustration about how criminals and miscreants respond to incentives and are deterred by a greater prospect of being caught, convicted and punished. In the case of lapel cameras, there is a greater prospect of been identified and recorded for later proceedings.
The introduction of personal cameras in New Zealand prisons in high risk areas lead to a large reduction in the number of incidents of violence and abuse towards prison staff. Chief custodial officer Neil Beales said:
The use of on body cameras has led to a 15 to 20 per cent reduction in disruptive incidents (which can range from very minor to more serious) in units where cameras were used, compared with units where they were not used.
Even hardened prison inmates respond to incentives and a greater prospect of being caught and punished.
The introduction of personal cameras is not a priority for the New Zealand police. Mention was made of a six year long budget freeze as one of the reasons.
The first randomized controlled trial of police body cameras in the USA showed that cameras sharply reduce the use of force by police and the number of citizen complaints.
In Seattle, where a dozen officers started wearing body cameras in a pilot program in December, the police department has set up its own YouTube channel, broadcasting a stream of blurred images to protect privacy.
