In an effort to "curb crime", DC police are going to cordon off entire neighborhoods with police checkpoints and require anyone coming there to provide identification and a "legitimate reason" to be there, or face arrest. They had wanted to perform door to door warrentless searches, but are not allowed to.
Yes, really. In the capital of the United States.
When I lived in Arlington, I used to love visiting some of the small bookstores in those parts of DC that lay outside of the shopping and government districts. They had really great books of African American history that I never saw anywhere else and that talked about things I had never heard of. Occasionally, police would ask me what I was doing in these neighborhoods, it being widely believed that a white kid from Arlington in downtown "chocolate city" was there to buy drugs. Would I go now, having to enter a police checkpoint and prove that I was really going to buy books? Nope. Not on your life. So, instead of taking those police officers and having them "walk the beat", DC is going to use them in a way that destroys the local economy.
Never underestimate the stupidity of the DC police force and government. I remember, back in high school, when go-go music got big in DC. You might expect the DC government to be happy about a locally-created style of music that was gaining national exposure and creating an entire cottage industry in the heart of the city. Nope. They waged a battle to close down the go-go clubs in order to prevent the violence that occurred in some clubs. And, of course, I'm no apologist for violence, but damn, there has to be a better way to solve the problem than setting up mini police states.
