I wouldn't describe 'safety' as the state of things after the last time feds glassed a right-wing adjacent group. When the feds 'glassed' Waco, a little known guy named Timothy McVeigh was there. He used it as inspiration to bomb a federal building at which there were 700+ casualties of which over 150 were deaths.

The feds were very much aware "Bundys" was not just the ranching family but a whole bunch of people and greater militia network. If they had glassed Bundy himself it would have been a total shit-show.
