I used to believe Kleck's estimate

I used to believe that Kleck's estimate of DGU's was correct, but
overwhelming evidence to the contrary has convinced me otherwise.

To the best of my knowledge, you have never accepted Kleck's DGU
estimates. At least not in the last 5 years that you and I (and Pim)
have debated guns, crime and 'Point Blank.'

Here's what I wrote about it back in 1991:

A most interesting paper! Like any good scientific paper it raises a lot of
questions. The estimate of 1M defensive uses arises from about 50 (4% of
1228) yes respondants. Don't you just want to have a follow-up survey to
find out the circumstances of those 50 defensive uses? Alas, the original
data no longer exists. I hope someone funds a larger better survey along
similar lines.
