That would be correct. She would however be liable for their actions as well as her own. Most clubs here that have issues hire outside security. BTW the Orlando shooter had a Florida G license (armed security)which meant he had to annually re-qualify with his 9mm.
Aha thanks.
And for liability, I would anticipate that all bar owners or at least all rational bar owners would use a corporate shield. Note— I am not a bar owner (or lawyer) so I am just talking through my hat here...
