There is a new review of Brian Doherty's book, Gun Control on Trial: Inside the Supreme Court Battle over the Second Amendment, over at The American Spectator.
The review captures the uphill battle that the Heller litigants faced in the District of Columbia:
When an employee on the Taxicab Commission once suggested that taxicab drivers be able to arm themselves for self- defense, a spokesman for then mayor Anthony Williams said, "The proposal is nutty, and obviously, it would not be entertained seriously by any thinking person." After D.C. readjusted its laws in the wake of Heller so that guns were no longer prohibited but regulated to the point of making ownership exceedingly difficult, Mayor Adrian Fenty justified it thusly: "I don't think [the people of D.C.] intended that anybody who had a vague notion of a threat should have access to a gun." Apparently the mayor doesn't know or doesn't care that once a threat is real, it's probably too late to go through all of the city's regulatory hoops.
