the whole area. >> security is intense all across the tri-state area. right now sources telling me that this is pretty routine, they get suspicious letters quite often but there's probably more attention because of the super bowl they are not too worried but will be testing what they have. as for security in general, as you said, it's pretty big deal, we're at super bowl boulevard, as would otherwise be known as times square. millions of people come here every single day but there's more because of the super bowl. it's a massive undertaking to make sure everything is safe. that's why you're seeing mobile command units and police department have them and fbi has them. a number of agencies have the command units inside their surveillance cameras and watching every square inch with real time surveillance that can spot somebody they say acting suspiciously or suspicious package of any sort. they also have radiation detectors, thousands of them across the city.
