You can put aside your tinfoil hat regard Richardson's role in the Los Alamos fire. It was started as a controlled burn by a low level National Park Service employee of Bandelier National Monument. From there it spread to Dept. of Agriculture Forest Service lands and about a week after it started, it reached the lab boundary. It destroyed more of the town than the lab, where most of the buildings were spared due to thinning of the forest (something the envirowhackos prevented for the Forest Service lands -- timber cutting is a no-no for them).
As for the rest of your chronology, I know nothing about Washington state forest fires, but I do know that Hazel O'Leary (and her successor Federico Pena) was likely more responsible for loss of nuclear secrets than Richardson was. In the spirt of "openness" which the liberals subscribed to following the election of Clinton, she ordered relaxed security at the labs and encouraged "scientific" exchanges between US and foreign nationals at the labs and overseas. It was during the period from 1993 though 1998 before he became secretary when most of the damage was done. What Richardson's part in the Energy Department's "open door" policy is still subject to debate. But he stepped into more sh!t than he caused during his 2 1/2 year tenure.
