Good example. I have been to N'awlins MANY times and have never felt unsafe there...and..I have never seen armed guards at restaurants and tourist sites....and we all know the crime issues in NOLA

Maybe it's the "feeling" rather than the reality. If there wasn't the armed guards in Grand Case would the visitor have felt safer because the guard is a sign of potential violence?
No guard...no feeling that they are needed to be safe.
Guard...they are needed to protect
