You have a right and a responsibility to provide adequately for your own self defense and the self defense of your loved ones. Police tend to be a reactive institution rather than a proactive institution when it comes to violent crime; meaning that they show up when called after a violent crime has been committed, not before. Therefore the prudent individual will take the steps necessary to make sure if a violent encounter heads their way, they are prepared to stop it and survive.
Do not go looking for trouble, but if trouble finds you then having good fighting skills, knowing strike points on the human body that will incapacitate an attacker, being proficient with edged weapons, knowing how to handle handguns, rifles, and shotguns will all be valuable skills if your life is on the line.
Violent criminals do not share the same moral values that we do. To them you are their meal ticket. They see you as nothing more than an obstacle to obtaining what they want. Reasoning and pleading will fall on deaf ears. What they understand is brute force resistance. Make yourself a hard target so it is not worth their effort to select you as their next victim.
