Brett Kimberlin received a 50 year sentence for his conviction for using explosives to cause injury. He has claimed that his conviction was based on evidence manufactured by the ATF. Here’s what Mark Singer concluded about Kimberlin’s claim as recorded in the Appendix of Citizen K (p. 377):
To believe that Kimberlin’s conviction represented a widespread effort to frame him required the postulation of a sophisticated, ingenious, and illegal network of his enemies—nothing less, it seemed, than a “conspiracy per se.” Sometime the ingenuity with which Kimberlin credited the ATF specifically seemed too generous. For instance, on 20 September 1978, the day of Kimberlin’s arrest and the impounding of the Impala, the ATF agents involved in the search did not have the lab results from the bomb scenes. If the government had wanted to lace the Impala, they would’ve needed to guess exactly which substance—Tovex, that is, not dynamite or TNT—would link Kimberlin to the bombings. Additionally, the ATF was unlikely to have known that Kimberlin was using Tovex to excavate his property three years earlier.
It’s interesting that, although Brett Kimberlin doesn’t trust the ATF to honorably deal with crime scene evidence, he is campaigning through his NRA Watch website to increase the ATF’s gun control authority.
