There was an unbelievable amount of information that has surfaced(after the fact) on the background and intentions of Cruz, that even a minimal investigation, in my opinion, might have prevented this terrible shooting. Much was known about the shooter's mental history, but rather than doing an in depth evaluation, he was passed back and forth between many different agencies, and remained free to carry out his "warnings". I think it is likey that the way his case was handled probably added to his frustration and may have given impetus to his actions. Trying to use this shooting to justify banning guns is just a continuation of liberals desire to take away rights given under the Constitution. The amount of information available on Cruz is so mind-boggling I may try to summarize some of the more salient points in a later post.
