Wow .. U know a lot of those crazy Muslim terriorist tactics . You are right , thats how they hide in the USA to carry out attack on American soil . Those terrorists are waiting for the right moment to strike .
several pre-emptive arrests have been made already in the u.s. the big one that was not sniffed out was the massacre of unarmed soldiers in a home military base by a muslim major. he was influenced and recruited by an imam for the heinous dastardly crime. he is in carceration and undergoing trial.
