Watch this video, taken from a police raid in Des Moines, Iowa. Send it to some people. When critics (like me) warn about the dangers of police militarization, this is what we’re talking about. You’ll see the raid team, dressed in battle-dress uniforms, helmets and face-covering balaclava hoods take down the family’s door with a battering ram. You’ll see them storm the home with ballistics shields, guns at the ready. More troubling still, you’ll see not one but two officers attempt to prevent the family from having an independent record of the raid, one by destroying a surveillance camera, another by blocking another camera’s lens.
