The background check for a mere firearm doesn't involve a picture. It does for the silencer/suppressor, but that doesn't leave ballistic evidence on the bullet or casing. He can actually reuse the serialized frame and suppressor and use only aftermarket slides and barrels that don't require a background check. The slides and barrels are what leave toolmarks on the bullets and cases.

For somebody to have created their own firearm from a kit, I would think he would know these regulations. Maybe he wasn't that smart after all.

FYI, communications are peer to peer in Signal's protocol.

Yeah, the summary was missing a conditional clause regarding the intent of the action, to prevent repair with an otherwise functional part.

If serial number anti-removal techniques are working to prevent repair now and in the future, they will also prevent theft now and in the same time frame of the future.

The sophistication of high-tier determined thieves is about the same as professional independent repair shops. The main issue a non-thief independent-repair-shop may need to overcome is whether or not it is illegal to circumvent the protection, which things like the DMCA aren't supposed to touch even now.

What the parent poster was proposing is that registration of the same serial number as already sold may be blocked, but a non-serialized or other-serialized party would be allowed. Currently the restrictions are designed to require a match in a central registry. The central registry if it exists can simply be made to allow new things not linked to a registered owner by the manufacturer already.

And of course, for vehicles and guns we use vin and serial number etching which is manipulable too, but it is still effective at least somewhat in tracking crime. I suspect things would be similar for such electronically etched systems.

And these electronically etched systems generally work by having a writable memory that can have its write system "burned" by triggering a "fuse" that permanently makes it impossible to rewrite it without destruction or wholesale replacement of the chip itself. The goal here is to protect the chip, which is what is generally proprietary here. This also works for firmware protection too, to some extent, unless you have some especially powerful equipment.

Oregon citizen and friend of Charlie (who was quoted in the summary) here.

The bill specifically bans parts pairing when made effective to prevent an otherwise functional part from being used for replacement.

You can still use part serial numbering to prevent theft.

Why are you commenting with claims before researching their veracity first?

The Toyota Hybrid Synergy Drive is described completely on Wikipedia. There is a 3-way continuously-variable gearbox and two electric motor/generators (of different sizes) on top of the ICE. They link together as needed.
