[S]o much of the tensions between police departments and minority communities that they serve is because we ask the police to do too much and we ask too little of ourselves. As a society, we choose to underinvest in decent schools. We allow poverty to fester so that entire neighborhoods offer no prospect for gainful employment. We refuse to fund drug treatment and mental health programs. We flood communities with so many guns that it is easier for a teenager to buy a Glock than get his hands on a computer or even a book and then we tell the police “you’re a social worker, you’re the parent, you’re the teacher, you’re the drug counselor.” We tell them to keep those neighborhoods in check at all costs, and do so without causing any political blowback or inconvenience. Don’t make a mistake that might disturb our own peace of mind. And then we feign surprise when, periodically, the tensions boil over. We know these things to be true. They’ve been true for a long time. [...] And if we cannot even talk about these things -- if we cannot talk honestly and openly not just in the comfort of our own circles, but with those who look different than us or bring a different perspective, then we will never break this dangerous cycle.

I recognize there is a certain presumptuousness in this, a certain audacity, to this announcement. I know that I haven't spent a lot of time learning the ways of Washington, but I've been there long enough to know that the ways of Washington must change. People who love their country can change it.

We cannot escape the prospect of nuclear war unless we all commit to stopping the spread of nuclear weapons and pursuing a world without them.
