This a typical idiot liberal proposal that demostrates their complete lack of knowledge on the issue. Maryland in particlular spent Millions of tax dollars on this program, over the objections of the "real police". The political suck-up chiefs of police supported it. Not a single crime was solved, REPEAT-Not a single crime was solved via this "technology" in 5 yrs!. It has been proposed elsewhere, but rejected. As a 42 yr. LEO, I know forensics does a major job solving crimes, but 98% of legal guns are not used in crimes, so it is a vast waste of money. The evidence at the scene will provide the information to solve the crime, not the "pre-indictment" of the people. If this "imprinting"technology is applied it will raise the cost of guns and ammo so high it will indirectly prevent firearms ownership( Isn't that a slick political way to ditch the 2nd Amendment!) Forensics works, but "we" didn't do anything to be subjected to it!
