Not suicide at all. He was going to bomb another place. The bomb had a mercury switch, and as he was pulling from his car he tipped it the wrong way, and it detonated. Candace is correct.

How can anyone be called an "insurrectionist" when they've literally never been charged with, hence never been convicted of insurrection?

Please turn down the dramatic background music. It's annoying AF and drowns out Candaces voice.

LSD does not *cause* mental illness. It can aggravate pre-existing mental illness, however (just like any other drug). And, contrary to what is said in this episode, negative life consequences due to "bad trips" are actually quite UNcommon. Much of the bad press concerning LSD stems from either government propaganda or urban legend. And "LSD addiction" is practically unheard of, so much so that you might say it does not exist! (See above about government propaganda.)

Too many episodes that sound like bad armchair psychologist who got info from detective shows, books, pop culture and other true crime pods. Oh and just fast Google search without looking more deeply. Show just don't sound like someone that did work on mental health field. Shame as this would have been new and interesting way to see crime.
