If you consider again, as in my response to Mr. Weston, applying the case of Australia, where we see the most documented example of mandatory detention and the human cost associated with it—and this was laid out by a group of Australian NGOs in a letter to Prime Minister Harper in December 2011. They documented that in the year 2011 there were six suicides in Australian detention centres and there were 17,000 instances of self-harm within these detention centres.
More than a decade after the introduction of mandatory detention as part of Australian policy, it has cost over $1 billion Australian over five years and has not effectively been a deterrent.
The human cost, as we can see in instances of suicide and self-harm, is quite high, but so is the financial cost. It was very surprising for me, when I did research, what those costs actually broke down to be.
