So I am thinking that - assuming that micro stamping is required - a well planned crook would just collect the brass from a couple of gun ranges, sort out his caliber, and then at the crime scene, police his brass and toss down a couple of handfuls of the collected brass.
Might be obvious that the scene was tampered but it sure would slow down the cops.
Crooks pick up shell casings at the range?
Easy solution...pass a law saying it is not allowed.
Duh? (obvious solution to any good Dem ‘intellectual’)
