In re Brickey is a very short opinion. Nunn v. State GA 1848 http://www.constitution.org/2ll/bard...nn_v_state.txt
is probably going to be one of the most cited cases by the court. Also remember in Heller the line about "Few laws in our nation's history come close to DC's, and some of those few have been struck down." They then explain GA's complete public carry ban and how the legislature can't ban both. The line about the few laws being struck down can only be construed as SCOTUS agreeing in Nunn's premise.
