That is why it is so important to be observant and constantly aware of your surroundings. And even more, if it is legal to do so in your location, arm yourself and be trained to use them.
“...if it is legal to do so in your location, arm yourself and be trained to use them.” — Man-made legality doesn’t trump the God-given mandates of safeguarding Life, Liberty, etc.
Exercise discretion, be extra observant but be able to fight effectively. Sure, being judged by 12 rather than carried by 6 will land you in jail but it sure beats your family having to bury someone who was submissive to the laws of fools.
