With threats going unnoticed, obviously these agencies are not cooperating enough. Given the technology that is available, the last several attacks should have been avoided. The San Bernardino shooters were posting on Facebook about their views. Surely someone noticed? Isn't advocating violence against some law? I've heard the average citizen unknowingly violates the law at least twice a week. This has to be one of them, doesn't it? Why make all these laws if you can't or won't enforce them?
