Shelling Out Evidence
“They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.” - Ben Franklin
The way I read it this it is just like a calibrated weight to insure a scale is accurate. It just establishes a baseline to insure all measurements are accurate and repeatable.
When you have to shoot, shoot. Don't talk.

If it were not for 'Standards', we would all just be cavemen.
With all the attempts to code firing pins (CA and NY for example) by law, it will be interesting to see if this changes up the game for the Progressive law makers.
Possibly in the near future, in CA, you might have to provide one or several spent casings (via the required FFL transfer) when buying a new pistol or rifle. I see it coming.
It is my understanding that chambers and breeches, like rifling, always leave distinctive and identifyable markings that can (and have) be traced to individual guns--which is why a certain LEO told me to always use a revolver to commit a crime as it doesn't leave casings behind as evidence. Some advice, huh?

Quite a few problems with the process. In order to be "searchable", the gun's exemplar has to be in the system already. That requires some form of "registry" ("Hey, everybody, just bring your gun down to the Police Department and let us have it for a few moments. We just want a couple spent cases and a little paperwork from you.")
Just like fingerprints- if they aren't already in the database, no telling who they belong to unless you have the person attached to them.
Only other way to match the markings to the gun is for it to have been recovered. In most cases, if you already have the gun, you can probably find out who owns it, but not necessarily who committed the crime with it.
Changing firing pins is fairly easy as is a new barrel. Nevertheless they will be able to identify many firearms.

That might be a start, m.
Most states (including mine) don't collect that casing and there is at the present time no common data base shared by all 50 states. Of course, there are also a few hundred million firearms that remain unprocessed - that is gonna be a HUGE undertaking (if it ever occurs).
Be a very dark day when something like that happens here.
Yeah, that's all great and wonderful. Standardization for a system that mostly doesn't work.
NY ended its own registry of revolver and pistol ballistic characteristics.
CoBIS or GUN DNA:A waste of millions of dollars, a waste of police manpower.
Short version: very few out of millions of records ever matched, and no crimes solved.
And I'm a little concerned about a system that gets calibrated or tested with just one exemplar. I'm sure the NIST guys are really bright, but it just seems a little weak in the confidence building department.
The only common sense gun legislation was written about 226 years ago.
I carry always not because I go places trouble is likely, but because trouble has a habit of not staying in its assigned zone.
