TFLers might consider attending, to help prevent one-sided coverage.
Knowing the Orlando Sentinel, a 95% TFL attendance wouldn't prevent one-sided coverage.
A significant attendance by TFL Members and kindred spirits will, however, prevent the "discussion" from becoming a one-sided hate fest about the evils of SYG laws.
Another concern would be who the pro-SYG panel members are. I see that one is the owner of a gun shop, therefore vulnerable to the charge of being biased for SYG laws for business purposes. It's also a well-known anti tactic to stack the panel with academics and law professors on the anti-side, pitted against inarticulate red-necks that can be portrayed as wild-eyed extremists on the pro-side.
