George Zimmerman's attorneys won't use "stand your ground" defense

[DanTex]

56. ...

1. In a self-defense scenario, the life of the attacker and the life of the intended victim are not equivalent

I agree. That's why it's so important that the increase can't be explained by justifiable homicides.

2. If the tool you're using can't measure the benefits, pretending that means there are no benefits is not legitimate

The tool can measure the benefits very well. The benefits would show up as less murders. The costs would show up as more murders. Pretty simple, you don't need to do any fancy accounting. Just count how many innocent people die.

3. Using a biased and/or unqualified estimator is likely to result in a bogus estimate

Right, but there is no evidence the estimator is biased and/or unqualified, and but even if you assume that the police reports grossly underestimate the number of justifiable homicides, you still find a net increase in murders.

4. "Back-of-the-envelope calculations"

Unlike you, an actual scientist reading the paper would judge by the content, rather than using this phrase as an excuse to dismiss the evidence.
