Denver mass shooter named his future victims in self-published novels.

1. I was bothered by the author's apparent position that law enforcement could and should have known.

The killer wrote ‘thinly veiled novels’ in which he killed the same people that he later attacked, and the police were advised. So what were they supposed to do about it? Arrest the killer before he acts? Our laws don’t allow for that, nor would we want them to. Warn the one(s) so described? The police don’t even have to try to save you during an assault, let alone warn you.
