In praise of judicial restraint
The manufacturers were faulted for making guns with features that supposedly appeal to thugs--such as concealability and resistance to fingerprints. But some people are legally permitted to carry concealed handguns, which means they need concealable ones. And miniaturization takes place in other products not used in crime. Even many law-abiding shooters like small handguns better than big ones, just as teenagers prefer iPods to boom boxes.
Fingerprint-resistant surfaces are popular among law-abiding sportsmen, because traditional shiny finishes are more visible to prey and more prone to corrosion. This innovation is no favor to crooks because it doesn't actually prevent police from getting prints off a murder weapon.
