California uses the technical feasibility of microstamping serial numbers onto a firing pin so as to require any new handguns added to the state’s “roster of safe handguns” have such a firing pin. The 25 micron relief of the stamping can be sanded off in like a minute so the tech is really just a de facto ban on any new designs being legally sold in the state
Oh I meant sanding the die off of the firing pin so it doesn’t stamp a serial number onto the casings; the projectile gets marked by the rifling upon firing. Wakmrow posted an article above about how the rifling analysis is subjective, unrepeatable pseudoscience but I don’t think it mentions that polygonal rifling is distinguishable from traditional land & groove rifling. So if a defendant is caught with, say, a glock, finding polygonal rifling on recovered bullets would make such analysis more damning in that case.
Probably just means even their made up pseudoscience couldn’t work
huh I thought guns had, like, microscopic “signatures” or serial numbers on the firing pin for some reason

Hmm, that’s only on the brass though, I guess marking the bullet would be significantly harder

Oh, so like how DNA testing is quite flawed, or lie detecting or body language analysis…
I’m starting to think that the police don’t actually know what they’re doing and rely on snitches to do their job for them.
