Data-Slicing
"Yes. That's because crime is down. According to every credible study.
Anyone who tells you crime in general is increasing is lying. Some types of crime may have gone up, but the overall crime rate has dropped considerably."
Depends, like everything else, on how you slice the data.
I can say, using the crime numbers supplied by my Local Authority, that violent crime has more than tripled within the area since 2001-2 (violence against the person, wounding endangering life, other wounding, common assault) - 1,826 in 2k1-2, and 6,253 in 2k8-9. Including all crime types, it has increased by more than 10% over the same period (17,328 to 19,229).
I'm surely not "lying" when I cite this, as I'm using exactly the same data that the LA use to prove how good they are at reducing crime, I'm just slicing it a different (and, I would argue, more realistic, way). I would also include the caveat that crime in 2008-9 is significantly lower than it was in 2006-7 and 2007-8, so it has reduced in the short-term from a peak high in 2k6-7.
