The capital of a country, especially one in a special status like Washington DC, should be a shinning star of perfection, nit in the top 20 hell holes you'd never want to be caught dead in at midnight alone.
That sounds like a reference to North Korea. If that wasn't your intention: the capital of a country is usually (but not always) also the largest city. The largest city will have the largest group of people on the fringe. By definition it will never be a 'shining star of perfection', but neither are they in the 'top 20 hell holes', they have more of everything, and that - unfortunately - includes more crime. But the DC version is a bit more complex in that the biggest criminals are not found on the streets but in various offices.
