Idk I think it makes perfect sense. Think of the oligarchs as someone actively firebombing the house in your analogy. It’s not just about getting the leg unstuck but stopping the ones causing the biggest issue

A parts kit always needs a lower. The lower is the part that is considered the gun legally and is registered and serialized normally. 3D printing the lower is what makes it relevant

You’re unaware of the existence of 3d printed Glock lowers? That’s all it was

You don’t seem very knowledgeable about the gun used in this situation.

All articles about what was found on him kept mentioning a metal slide and barrel along with a regular Glock mag, that heavily implies it was just a 3d printed Glock lower so basically just a regular Glock. The only way it would “leave no special markings on the bullet” would be if he used a gun with a plastic barrel, but I believe the FBI said shortly after the og liberator was released that it leaves enough plastic behind to be traceable.

In practice the gun is a regular Glock, that would be easily identified as not being legal in a few states. My guess would be that they weren’t getting rid of it because it’s still a perfectly serviceable firearm and he might have been planning on using it again or at least it probably seemed like a good thing to have when he was in fight or flight mode.

If you really want to get rid of evidence the metal barrel is going to be the most important thing to get rid of as far as being linked to a shooting. Ghost gun is just bad in general unless you are in one of the states that says it’s fine

It’s a 3d printed Glock lower. It’s not meant to be discarded after a single use any more than a regular polymer lower would be
