Please define just what a suspected terrorist would be like, just what would qualify your neighbor to be one. This is in no means being said in any offensive way, I am seriously just asking the question.
Don't worry DW, when you see one the hair on your neck will bristle, the adrenalin will pump and your sense will become sharpened. Self preservation will kick in and all qill be right with the world.
By the way, how do you know a criminal when you see one?
