Boot camp the answer for 'tough' kids?

Gareth Morgan and crime experts are urging National to lock up its boot camp policy and throw away the key.

The party unveiled its hardline new youth crime policy on Sunday, including fines for parents of kids caught wandering the streets at night and an army-run boot camp in Waiouru for the worst youth offenders.

"These are tough kids - 150 out of hundreds of thousands between 12 and 17 who already have a track record, who have committed very serious offences at a very young age," Prime Minister Bill English told The AM Show.
