Two hours before the attacks the next day, Watson told a prison counselor that he urgently needed to be transferred back to higher-level security "before I really (expletive) one of these dudes up," but the counselor "scoffed and dismissed" him, the letter says.
Watson said he returned to his housing pod.
"I was mulling it all over when along came Molester #1 and he put his TV right on PBS Kids again," he wrote, according to the newspaper chain. "But this time, someone else said something to the effect of 'Is this guy really going to watch this right in front of us?' and I recall saying, 'I got this.' And I picked up the cane and went to work on him."
Watson said he then left the housing pod to find a guard and turn himself in, but on the way, he saw "a known child trafficker, and I figured I'd just do everybody a favor," Watson wrote. "In for a penny, in for a pound."
