So, why am I saying that you shouldn't rely on the police to protect you against crime and civil unrest? Because it isn't their job!
It is a well-established principle of law that the police have no affirmative duty to protect you even if they know that you are in immediate danger or currently being victimized.
On 27 June 2005, the U.S. Supreme Court said this clearly and distinctly in ruling on a case called "Castle Rock v. Gonzales". It's all laid out for you in the charming story of Three Dead Children In A Pickup Truck.
The truth is that self defense is a personal choice that requires you to make personal decisions. I'm not talking about choosing if you should protect yourself. I'm talking how you should protect yourself.
Consider the guard dog. If you are afraid of dogs or just don't like dogs, what's the sense of getting one?
Think about guns. A gun is not a magical talisman. You can't make a bad guy vanish by just waving it around. You have to search your soul and ask whether or not you really could point a gun at somebody and kill them. If the answer is no, don't get a gun for protection!
I suggest that you learn about all of your options, and choose those that suit you.
