I would rather Americans be cautious and alive than classy and dead. Did you see my post where these things are showing up as weapons too?. Yeah this may be a money maker but we should follow where the money is going. When some things don't seem on the up and up and actions can't be explained I think it needs checking out. I'm really not in to being "right" Actually I hope you turn out to be. Time will tell, I guess.
Then why not just arrest everyone just to be cautious.
Terrorists are a real threat to the country but so is hysteria. If we keep crying wolf, we're going to miss the real terrorists.
