Glad to know someone other than myself sees the humor in this.
Too many dead bodies of late to see a lot of humor in your question and people do tend to over react on the theory that it better to be safe then sorry.
I suggest you go light on making such statements on the net unless you wish for a visit from your local law enforcement in order to drag you away for a few days of mental health examinations.
Before 911 I and my wife was on a tour of the Hoover Dam when the tour guide made some comments relating to the steps taken to guard the dam from sabotage during WW2.
I then begin to suggests to my wife means of mounting an attack on the dam with special note of the means/methods successfully used by the English in attacking German dams during that war.
My wife told me to shut up for some strange reason.......
