In fact, the calculation is simple. It's based on a study conducted by an expert in cost-benefit studies, Mr. Ted Miller. He conducted a study on the cost of firearm-related deaths in Canada—those costs have been adjusted to current dollars. He estimates the value of one saved life at roughly $1.5 million, just considering the direct and indirect costs. Those costs mainly consist of the lost productivity of the people who die. These are often young people who will not produce during their working lives, and so on.
If you do the calculation, it's quite easy to come to the conclusion that we're saving quite a bit of money for Canadian society as a whole.
