None of us is safe from police raids

Imagine you're Cheye Calvo, the white mayor of Berwyn Heights, an affluent part of Prince George's County. Coming home one night in late July, you find on your front porch a large package that, unbeknownst to you, happens to contain a lot of marijuana. As it turns out, your spouse is the victim of a drug-smuggling scheme that targets innocent customers in the UPS system. You bring the box inside; moments later, the SWAT officers standing by break in and shoot your two beautiful Labradors. As the dogs lie there bleeding to death, you're held in the same room, handcuffed for hours. Nearly a month later, you have yet to receive an apology.

Because of who he is, the nation knows what happened to Mr. Calvo a few weeks ago. Here's what most Americans don't know: There are perhaps 40,000 such raids each year, according to a Cato Institute report, "Overkill: The Rise of Paramilitary Police Raids in America."
