---Why is this a problem to NRA?

How about if a semi smart crook goes to a range where dozens of people have been shooting all day and leaving micro stamped cases lying around, and said crook pics up a bunch of them, then he goes and shoots up a store while he's robbing the place and then tosses all those shell casings on the ground.
If you were at that range and that crook picked up a shell casing from your gun and left it at the crime scene, YOU have just become a suspect in a police investigation.
You didn't do anything wrong so you have NOTHING to worry about right?
Are you going to continue to believe that when the police come to your place of work and drag you out, put you in a police cruiser, and take you to the station for questioning?
How about when they show up on your doorstep with a search warrant and tear your house apart looking for evidence?
Here's anouther thought to consider. How many crooks do you think go out and buy fresh quality brand new ammo for their guns? They're crooks and most will buy the cheapest ammo they can get their hands on, and those are reloads. A shell casing you fired from your micro stamped gun a year ago, might have been fired from other guns several times before crook gets his hands on it and fires it while commiting a crime, but what's going to happen if the micro stamp from your gun is the only one that can be read clearly? Again, your the target of the investigation now.
