Group therapy curbs sex offenders' recidivism: ministry

A lot of real hard liners on this website, some of the things they suggest would've been severe even in medieval times.

The recidivism rate for executed convicts is zero.

Ist chance: therapy with a dose of hard labor. Good.

Second chance: as @disillusioned suggests, but blunt rusty scissors maybe a cheaper, quicker option.

Chemical castration would also work.
