As far as taking any action- I would suggest first waiting to see if there is any legal recourse here. Gun owners need to take the high road on this one. Whether we like it or not, the reality is that CCW permit holders will likely be demonized for the slightest impropriety in action and Brantley will be defended for his.
First- explore the legal avanue. Then seek some fix through the legislative process.
As much as I chuckled when I saw the author's home address, personal phone number, property tax records, and google maps image of his home posted on the web, I think we can do better than stooping to his level. And, as much as posting that info might make a point, I doubt it would bring about any real change.
Just my .02. I'm all for recourse, but let's do it the right way.
