I'm 70+ years old and no longer have the speed, agility, and strength I had 30-40 years ago to engage in 'kung fu' with any criminal/thug whom attempts to harm me, those with me, or engage in any other crime against me/us.
In my lifetime I have seen too many a "street fight" where once the victim(s) are down and on the ground, the kicking and stomping, often of the head, begins. If lucky, the victim(s) will live, but often with injuries, some lifelong, if not out right killed by feet and fists, etc.
I consider any confrontation that threatens or could lead to physical assault and harm to be a potential "Life and/or Death" encounter.
Hence I have a Concealed Pistol License (what my State issues) and will be packing a pistol (and likely a spare mag or two) in public. I also usually carry pepper-spray(mace) as a first choice if the situation allows.
What I and many like myself would rather see is for you and all other "anti-gun" sorts whom wish to disarm we whom want to protect ourselves with "great equalizers", to start wearing large yellow ribbon armbands on one or both sleeves so that;
1) We law-abiding, legal firearm carriers will know not to use our firearms to protect you and your sorts from any criminal types whom might be attacking, or engaged in crimes against you. (After all, we risk legal and civil court hazard anytime we do such.)
2) Wearing the yellow ribbon will indicate to criminal sorts you are willing to be victim of their crimes and assaults, and don't wish for citizens to intervene on your behalf. This will help the criminals and thugs in their legal defense and spare the rest of us as from complications of coming to your defense.
