DC on Parker case (Wash. Post).
Here's a WashPo op-ed by the mayor and something called the Attorney General of DC on the case.
Not terribly illuminating. (1) Nevermind the text and history, the courts didn't recognize this right before and thus shouldn't now; (2) the 2nd Amendment only covers the Federal government ... uh, and while DC is part of that government, it ought to be treated like a State anyway; (3) complete prohibition of handguns is "reasonable regulation" because you can own other types of arms (not mentioning... with a police permit, and only if they are disassembled or trigger-locked. No sense making life dangerous for DC's criminal class).
