Reg, I think you're over simplifying this. There are many other factors to consider, which 11mile has covered well.
Comparing the amount of people dying each year waiting for organs to those that are murdered may make a deeper impact on some people, but just saying that and not giving any more information is stupid.
First, what is the murder rate in Canada?
Second, the comparison is just not logical... some of the people waiting for organs may have lived another 2-3 months. I had an Uncle with liver cancer. He could have had a liver transplant that would have extended his life another 2-4 months but he couldn't get one. He told us he wasn't that upset. Your statistics likely include people like him, which happens to be a fairly large amount of people as cancer either is the leading cause of death in Canada or will be soon.
I hate comparisons that many people use to try to make their point have a larger impact. The number of people murdered has no corrolation to the number of people that die waiting for an organ transplant.
In the future just say "(this number) of people die each year waiting for organs". Not only does it give more information, but it doesn't mislead those who do not think through the comparison.
Sorry, this is just one of my biggest pet peeves

I'm all for signing your donor card (personally I would love an extra few months alive if I needed one), but completely against invalid comparisons.
