Even though they have described to me such unfathomable actions as hacking off the heads of still-living victims, it is something other than mental illness that drives their violence. Their sanity is disconcerting because, if they were simply mad, it would be easier to accept horrific actions like leaving piles of headless corpses in town squares.
Instead, we have to face up to the hard reasons why thousands of young men (and some women) with full mental faculties have become serial killers. These reasons should be taken into account by residents of Colorado, Washington state and Oregon when they vote on referendums to legalize marijuana next Tuesday.
