Foreign Correspondent: Gunsmoke

It's where heavily armed citizens take border security into their own hands and it's where, in the words of one prominent critic, you can have a long criminal record, a history of drug abuse or be on a terrorism watch list and buy a gun 'quicker than it takes to order a burger and fries at McDonalds'. It's also where, in January this year, a gunman massacred six and tried to kill a federal politician. Welcome to Arizona.
