Another stupid idea
Here you go. Another reason that sounds good rather than a good, sound reason. Lawmakers Consider Stamps on Bullets.
Krazyfornia is at it again. They want someone to invent a gun that stamps a serial number on every bullet it fires, so that they can trace the bullet back to the gun owner. Anything else is considered "unsafe."
As with any technology, it can be circumvented or deactivated. I thought up 5 different ways to get around this stupid idea just writing this post. Imagine how many ways I could figure out around it by really thinking about it.
Anyway, this is just another way to get guns out of the hands of law-abiding citizens, not the criminals. The criminals don't care if you can trace the gun, they probably stole it (thus rendering any tracing ineffective) and they will throw the gun away after the shooting.
I'm glad I don't live there any more.
