This app is intended only for ENTERTAINMENT! Any mention of Gun-Free Zone (GFZ) "protection" does not imply any real protection. For any trouble in a GFZ the only thing to do is to get away and get help! The user options in this app are only meant to humorously make the point that there is no protection in a GFZ. The only recourse is to get away and get help! The app options are ridiculous and meant for laughs. So, enjoy a laugh and please do not take the "protection" seriously.
