Actually, Pax, I have seen just that. Endless posts about how he is insane, has a serious mental disorder, was on medication, was disheveled and babbling, showing significant signs to his family, school, etc., that he was insane and needed help, that his family knew he was ill, were afraid of him, begged him to get help, etc., all without the words, "I bet, " or "Maybe" or "What if" or even, "IMO".
These were accompanied by references to him as the "young man" and how the mentally ill cannot be held responsible for their actions.
I have seen several posts that excuse what he did as a product of a mental disorder the posters assume he has, either by creating evidence out of thin air or expanding on reports. For example, a staffer in a gun store felt he seemed a bit off or strange becomes "gun store owner was scared of [THE COWARD].
So yeah, people are not just discussing the possibility that this creep has a mental defect, they are stating it as if it is a fact and some posters are actually stating that he would bear no responsibility because he does not know right from wrong or cannot control his actions.
I, for one, don't appreciate that. I'd like to see a lot more assumptions and speculations prefaced with language that indicates it is an assumption or speculation and I don't like the general tone in some posts that a person with a mental problem is not responsible for their criminal conduct. That's an insult, IMO, to those who were murdered in Colorado, by a guy who planned for months.
