Registration records would create a comprehensive database of all guns and their owners. During a criminal investigation, when a gun was recovered from a person who was not its registered owner, that person would face serious penalties. But so, too, would the registered owner if he had failed to report that the weapon was no longer in his possession.
Under this system, anyone selling or possessing unregistered firearms would face huge legal risks. Overnight, gunrunning and other illegal arms trafficking would become easier to prosecute.
Emerging technology will also help. Registration could include recording the unique characteristics of a firearms barrel. That, combined with stamping ammunition with identifiers, could someday make shooting at someone much like leaving fingerprints at the scene of the crime. Firearms offenders would become far easier to catch, and the prevalence of firearms crime would decline.
Is there a registration database somewhere in the world where crimes have been solved using the registered info?
I'm sure that all the criminals and owners of illegal guns will line up to register them.
They can't be charged with a crime if don't so why wouldn't they?
Are you kidding me? Barrel characteristics? Stamping ammunition?
Somewhere there must be a prize offered for stupid ideas and Mikva and Rosenthal must have been there to write them down.
