Saw this on Stuff.
Police have arrested 78 people, many drunk, for night-time breaches of Christchurch’s central city cordon since February’s earthquake.
Figures release by police today showed the number of arrests was highest in May, when 18 people were arrested for being inside the red zone without permission.
I was talking to someone recently who’d been on the cordon.
Basically, they just check people going in and respond to alarms. Apparently they have the entire place fitted with sensors. People (usually drunk as the article says) think they’re out of sight and can simply sneak in, but get caught because they trip a sensor. The army guys simply give the cops a call, who turn up with dogs and track the person.
I jokingly asked if they were lasers. Apparently so, but not the sort you find in James Bond moves I guess.
