You should probably try to understand the concept before you post more foolish remarks. Posters on this forum have a responsibility to be factual or state when their writing is unsubstantiated opinion.
Why do you believe this technology has anything to do with bullets and/or firearm barrels?
The technology is here and it works. It deals primarily with fired shellcases and the telltale marks left on the shellcase after firing a cartridge in a particular firearm. Moderate gunsmithing skills and tools are needed to offer even a fair chance of defeating the system. All machining marks must be removed from the firearms breech face, firing pin, ejector, extractor and chamber. Please don’t waste anyone’s time by rebutting that barrels can be changed, firing pins can be changed, etc.
Constitutional issues abound but you are barking up the wrong tree to fight this on a technology basis.
you are barking up the wrong tree to fight this on a technology basis.Do you own a firearm? Where do you get your information from? Do you know how easy it is to stone and polish the hammer? Or how simple it is to replace the firing pin? Do you even realize that most firearms do NOT eject the shell casings automatically so how exactly would they retrieve them to match the fingerprinting? Not to mention that if this system goes into effect the perps could just pick up the shell casings from firearms that do eject them. Do you even realize that you can get a "shell catcher" for just about any semi-auto firearm and that it will then store any ejected shells; therefore there will be none to be found???
Moderate gunsmithing skills and tools are needed to offer even a fair chance of defeating the systemJust about anyone and everyone who owns a firearm has these skills or has the capability of learning them. Why? Because anyone who owns a firearm and actually uses it has to clean it and doing the things mentioned previously are not any harder than what one alreadys has to do to clen their firearm. It's not rocket science by any means.
