With all due respect to law enforcement, 'law enforcement' is just that -- they enforce the law. They are not tasked with protecting anyone and unless we want one officer per person, they cannot protect us. They can only be one place at a time, and basically, they arrive after the fact. It used to be -- they would be there to draw a chalk line around your body, but now in the era of suicide bombers, there isn't enough left of you to draw a chalk line around. Look at London -- surveillance cameras every few feet, but that didn't stop the bombings, it helped in apprehensions after the failed bombing, but you are dealing with fanatics that want to die and take as many of us with them as possible. It is up to the individual to protect himself or herself and their family. You cannot look to any agency or government to protect you, they cannot do it -- and you should not realistically expect them to do it.
