Alan Gura filed his clients' reply brief (.pdf) today with the Supreme Court for the upcoming gun rights case McDonald v. Chicago. This is the final brief to be filed by either side and it's a definitive piece of work. In fact, it makes Chicago's efforts look a little amateurish by comparison. There's plenty to quote from, though I think this one sentence sums up nicely:
Unable to articulate the correct standard for substantive due process incorporation, or interpret the Privileges or Immunities Clause, Respondents [Chicago and Oak Park, Illinois] offer irrelevant political arguments against application of the right to keep and bear arms against the States, failing to accept that the decision to secure the right in our Constitution has already been made.
Next up are the oral arguments on March 2. For Reason's coverage of the case so far, see here.
