while the authorities track the cases to someone's firearm and find that he was a regular shooter at some range and another individual picked up the brass he left behind and spread it at the crime scene.

I used to reload my own ammo and I would make an effort to recover all my brass. Shell cases from a semi-auto pistol fly everywhere. Some ends up beyond the firing line where most ranges will not allow you recover it. Most ends up behind the firing line but with a number of shooters on the line is difficult to find among all the brass. I was lucky to recover 45 out of 50 cases. Many shooters who don't reload don't bother to pick up their brass.

The microstamping idea is just another "feel good" law which will increase the cost of firearms and accomplish absolutely nothing. The idea appeals to those who have little or no understanding of firearms but want to see firearm violence decrease.
