I ran across this rather fascinating web site:
An article about the technology and the lobby group:
I find it fascinating because, you have a patent holder (monopoly) hiring a lobbyist in order to jump start their business model. Talk about a 21st century business...
Never mind that the idea of bullet stamping is simplistic. Presumably they would ban reloading, reloading components, and reloading equipment in the process.
By analogy, maybe they should only allow the sale of knives that have a unique cutting pattern to each knife. Then each knife will be registered and recorded in a national database (requiring a background check). That way police will be able to quickly track down the perp in a stabbing case. Makes complete sense if you don't know a lick about knives.
