If you can easily spot a terrorist then the person was never a terrorist,most terrorist are not easy to

spot by someone who is not a professional in the security system,though there are some things that can be easy to use to know if someone could

be a suspected terrorist but it is rare these days to easily spot a terrorist,and the terrorist themselves would want people not to suspect them so they play along and pretend to be what they are not,i think the way to spot a terrorist is from the body

language of him or her and often they are checking their wrist watch or adjusting their clothes or acting jiltery...
