I agree with these statements:

1) never let your guard down, ever
especially in these days of terrorism and just plain psychos everywhere

2) you have to be aware of your surroundings

3) I doubt since this was a hotel employee, that he would be permitted to have a gun, even with a concealed carry permit -more than likely with this many attackers, they would probably have taken the weapon from him and used it on him

4) it proves that you can't depend on security or the police or anyone else to protect you
