to be clear on the “3d printed guns explode after 3 shots” thing.

It depends. If it’s 100% 3d printed parts, including bolt/slide and barrel, then yah, a few shots is the most you’d get out of it.

But most “3d printed guns” are using off the shelf barrels and bolts/slides, parts that are usually not registered and tracked. The parts that are register and tracked are usually the parts that hold trigger assemblies and grips, things that can be made of plastic since they’re not directly handling the stress of firing.

So the fact that the gun (the suspect was arrested with) is intact doesn’t mean it was never used. It also doesn’t mean it was definitely the gun used.

The situation still seems weird, but, we’ll see what the different parties have to say on the matter when they go to trial.
