In my experience, and I believe in the experience of many of my colleagues who defend these people on a daily basis, there's not necessarily any correlation between the number of offences on a person's rap sheet, a person's record, and the extent to which the person poses a real and true danger to society.
In fact, my clients who have the longest conviction records are the ones who have the greatest mental health challenges. They cannot understand, and for that reason they miss court dates. They are compulsive in their behaviour in terms of not showing up for court or compulsively stealing and things like that. That doesn't necessarily correlate with the people we are seeking to target as being the most dangerous and reckless people in society.
