To see if there is a deterrent effect, the Act actually needs to be in place for at least 20 years. Offenders actually have to serve time, get out, commit another serious offence—not a petty offence—and be incarcerated again, serving a full sentence before being released again. And because we are talking of serious offences, this means that on the second strike the full sentence requirement is probably going to be for some lengthy period, such as five years for the head stomper that I just told you about.
