How do you block firearm parts at the printer level without analyzing and judging the files a user provides?
Even if this was possible (it’s not), most printers don’t have the kind of processing power needed to reverse slicing back into the solid object so that it can be compared with banned parts. They’d either have to put in much larger computers and spike the cost per unit or do it server-side and be always-online.
The intended usage of a rubber bullet launcher is to shoot it into the ground in front of the target. It’s rubber so that it will bounce upward, knocking out their legs.
Targeting a person with direct fire is assault with a deadly weapon and should be prosecuted as such.
As far as I can tell, the frog incident was not real-world. It was a police department vetting a system by doing fake test stops. They did one with Princess And The Frog playing in the back seat and the transcription system interleaved the traffic stop and film dialogue, then took that at face value for the summary.
System still sucks, but at least they were testing before blindly relying on it.
The food service staff all go through e-verify, so the government already stated they are authorized to work.
ICE won’t care.
