Mr. Litton, however, could not legally buy a gun because he was a felon. Mr. Honea said investigators believed that the handgun that Mr. Litton used was a homemade, untraceable gun made of parts from different weapons, often called a “ghost gun.”
So, what did California's gun control regime accomplish here?
The California gun control kept the crazy murderer and convicted criminal from buying an arsenal. He had to buy parts and assemble them into a functioning firearm, something that has yet to be regulated because gun advocates complain that restricting access to parts is an unnecessary government overreach.
If the shooter (not murderer, hopefully) couldn't buy an arsenal, why didn't he build one? A single weapon appears to have been enough for him and it wasn't as if the attack stopped because his DIY gun was somehow significantly inferior to a store bought one.
We don't know all the details surrounding the guy or the incident, so I'm willing to table discussions about what he built and what regulations might have prevented it until we know more. But building a ghost gun is significantly more difficult than buying a legal firearm, and the ability to circumvent a regulation isn't an argument for removing the regulation. He wanted a gun to commit acts of violence, and he couldn't buy one. He found another way, and we should be looking at additional restrictions, not looking to criticize the ones that functioned as intended.
"investigators believed that the handgun that Mr. Litton used was a homemade, untraceable gun made of parts from different weapons"
I wonder what they mean by that. The frame of a glock (for example) is the only part that is considered a firearm by the govt. That is what is registered because the collection of parts won't work without it
The rest is all just parts that can be bought/replaced as desired by the owner. It's just steel tube, springs and other small parts. That is what makes it popular - simple and reliable design. (btw the box in the photo is not relevant to this comment)
So did the guy mix and match factory pistol parts, scrape off serial numbers or 3D print/machine a frame or other components?
