Not that I'm ever going to vote for the Liberals, but they do make a point in that letter...
The continued increase in many crime indicators, and the fact that the overall crime rate has not decreased with the Liberals in power, has heightened cause for concern. We no longer live in a country where we can sleep with the doors unlocked as we had twenty years ago.

How many people didn't lock their doors in 1985 but do now?
I'm pretty sure that the crime rate has gone down in both Canada and the US. Later on that same page it even says "the crime rate went down 1% last year, but the murder rate went up". Kind of confusing.
"Crime Task Force" gets it's own tab on the left hand side along with other issues like "The Leader" "The Party" "Press Releases".
Fearmongering or not, it looks to me like "get tough on crime" is going to be a big part of their platform.
