OK. Let's say starting tomorrow, all handguns have a fingerprint lock/unlock. Every single one manufactured.
In 90 days, everyone will be sharing "workaround" and even kits to circumvent.
Prices on the current handguns will go up, as most everyone will only buy those, as they're not made any longer. Look up the price of a Colt Python - a firearm that Colt quit making.
If one has basic knowledge, you can take pipe, potassium nitrate, sulphur, and charcoal along with a handful of nails - and have a homemade hand cannon.
You can't outlaw fire because folks get burned - the cat is already out of the sack. Knowledge is out there. CNC machines will build you a 1911, Glock, AR-15, and AR-10 right this minute.
Folks kill or prey on others one way or another if they've made up their mind to do so.
At least those who may be smaller, slower, weaker, or less agile - can defend themselves with an equalizer of sorts - a firearm - and they are used to do just that by good people - every single day.
You have a rabid fox, a crazy pittbull, or coyotes attacking your own animals - you can put a stop to it - and have that right. It's a right -
SOB is drunk or on drugs - kills one or more in a wreck - you outlaw cars? You blame cars? You outlaw cars?
Simple minds don't really think things out - which is exactly why Progressive philosophy is totally retarded. It's one thing to be dumb as ****, but if one keeps their mouth shut - they can be dumb as **** and no one will ever know.
