How are we different from a police state?

And what can be done about it?

According to the Charlottesville Daily Progress, shortly after 10 p.m. on April 11, the 20-year-old U.Va. student bought ice cream, cookie dough and a carton of LaCroix sparkling water from the Harris Teeter grocery store at the popular Barracks Road Shopping Center. In the parking lot, a half-dozen men and a woman approached her car, flashing some kind of badges. One jumped on the hood. Another drew a gun. Others started trying to break the windows.

Daly understandably panicked. With her roommate in the passenger seat yelling “Go, go, go!” Daly drove off, hoping to reach the nearest police station. The women dialed 911. Then a vehicle with lights and sirens pulled them over, and the situation clarified: The persons who had swarmed Daly’s vehicle were plainclothes agents of the Virginia Department of Alcoholic Beverage Control. The agents had thought the sparkling water was a 12-pack of beer.

Did the ABC’s enforcers apologize? Not in the slightest. They charged Daly with three felonies: two for assaulting an officer (her vehicle had grazed two agents; neither was hurt) and one for eluding the police. Last week, the commonwealth’s attorney dropped the charges.

The agents’ excessive display of force is outrageously disproportionate to the offense they mistakenly thought they witnessed: an underage purchase of alcohol. But in a sense, Daly got off easy. A couple weeks after her ordeal, a 61-year-old man in Tennessee was killed when the police executed a drug raid on the wrong house. A few weeks later, in another wrong-house raid, police officers killed a dog belonging to an Army veteran.
