What especially bothers me about Kennestone is that they outright lie on their sign. They post a code section and claim that it's illegal to carry there, but the code section in question (which they didn't get right, anyway) doesn't say anything about hospitals.
Brandsmart U.S.A. I'm not sure if they have it posted, but when I worked there their entire security staff was constantly looking for people carrying firearms. Sad because they missed more people stealing trying to kick out law abiding citizens.
