I spent 13 years as a DC police officer, and rest assured the thugs will cover their faces whether ski masks are sold locally or not. I once caught four murder suspects in a car wearing surgical gloves, handkerchiefs over their faces and carrying pistols in their laps. They were all high on PCP, too. Banning ski masks is idiotic.
Now, if they would start actually handing out prison time when people commit crimes, maybe we would get somewhere. Nothing like running across a 16 year old who already has two armed robbery convictions.
