Safety is an illusion that we are selling our freedoms for.
I wholeheartedly agree with everything you stated with the exception of the above statement. Safety is a state of being you generate. It is a status of prepared existence. No you cannot prepare for every occurrence. No need to worry if you will get shot by a sniper, blown up by a nuclear strike, or hit by a falling meteor. You can't prevent or minimize those things. You cant avoid lightning strikes either and they are much more likely.
Recognizing what you can avoid, minimize, or eliminate with precautions, premeditation, constructive habits, and (dare I say it!) forearming yourself is where safety begins. Training and rigorous execution of the aforementioned is how safety is generated. Expecting safety from external sources is complete insanity. Just about every other person, law enforcement included, will put their life ahead of yours. This is natural and should be expected. Add in that old truth "when seconds count, the police are minutes away" and the list of parties responsible for your safety when it really matters drops precipitously. So when life and limb are on the line, how then can you have the expectation of safety from someone other than yourself? The hard truth is that in almost every circumstance you can't. To expect otherwise is to surrender your self determination to the hands of "fate" and the tender mercies of criminals.
An exception to this would be certain friends, my children, and my wife when I am with them. I will put myself in harms way, lay down my life if necessary, to prevent harm to them. While this dedication to the life of others may not be rare among friends and family, it is exceedingly rare with strangers. I can't stress this enough: Do not expect strangers and law enforcement to save you when the shit hits the fan. Rely on yourself, train yourself, take precautions, act intelligently, and know that you will win no matter what. And if winning means dying to save those you love or those you decide should live, act decisively and without restraint.
Sorry for the rant, but this is something I feel strongly about.
