No, you are misunderstanding. The filing on the gun being proposed is the device that stamps the soft brass cartridge with a unique identifier to show which unique firearm expended this cartridge when it was fired.
If the part of the firearm that is capable of stamping that unique identifier has been obliterated by removing the stamping die, then there is literally nothing ever stamped into the cartridge to be recovered by any means, chemical or otherwise.
This bill modifies the existing law from currently requiring that the firearm stamp TWO unique identifiers on the expended cartridge to just ONE identifier in 2022, based on the theory it supposedly will make it less complicated for gun manufacturers to introduce firearms that meet the states firearms specification, all so the State of California can proceed to test and certify more guns that meet their requirements, and thus remove more obsolete non-stamping guns from the list at the rate of three older guns for each new approved gun. At that rate, through the law of diminishing returns, using this negative feedback system, eventually the state would get to just ONE approved firearm that would be legal to sell in California.
All based on a specious theory that crimes can be solved by finding expended brass on the floor of a crime scene that would lead authorities to the buyer of the gun used in the crime, and therefore the perpetrator, ignoring that most such crime used guns are stolen. Expended brass is seldom if ever been used to solve a crime. A criminal could also use a revolver that does not expend brass, retaining it in the cylinder, or are these brilliant minds in Californias legislator going to pass legislation requiring criminals to deposit expended revolver brass in a convenient drop box, placed by the state for expended brass recycling at all crime scenes? Why not have a convenient fingerprint pad by the exit door and require all perpetrators leave an imprint of both hands as they exit? Oh, and please, spit into this tissue paper and deposit it into the appropriate sanitary receptical on your way out. . . Dont forget to snarl for our camera, too.
No one has thought about the 5th amendment, not to mention 1st amendment implications of forcing shooters to PRINT something against their will. This is, after all, enforced speech, to imPRINT, something on these cartridges every time the gun is fired. YOU WILL SAY THIS when you pull the trigger, using this PRING PRESS, or Type writer on this cartridge. You MUST sign your imprint here. You have no choice in the matter if you want to exercise your 2nd amendment rights. The unconstitutionality of this is violating many constitutional rights.
Wow. Thank you for the thoughtful and informative post. You’ve explained it so even I can understand.
