THIS ABC NEWS REPORT IS NOTHING WE DIDN’T KNOW, but it’s nice that it’s being reported:

Two related California studies to be released this week conclude it is currently impractical to catalog the ballistic “fingerprints” of every firearm in the state.

Recording every firearm made and sold in the nation’s most populous state could be overwhelming, according to an internal California Department of Justice report obtained last fall by The Associated Press. . . .

Given the miserable failure of Canada’s gun registry, it’s no real surprise that a California bullet registry would be, well, a miserable failure.
