Wouldn't it be more the National Guard, not the Army in this case?
That actually depends what the threat is, or more accurately, where it is. In America, it is illegal for the military to be deployed in domestic matters. That's the job of the police. Of course, if you can claim the threat is of international origin (declare it terrorism and you're set), then the Army can get involved. As far as that law is concerned...things like the FBI and US Marshalls count as domestic agencies even though they may be acting abroad. I'm not sure where the various states National Guards or the Military Police come in... The Guard might count as both. Formally, the Army, Navy, Air Force, Marine Corps, and Coast Guard count as the regular army. The National Guard formally counts as the militia.
That wouldn't work anyway...the containers they use to transport nuclear material are opaque to x-rays because they tend to be made of very thick lead. Lead is a great shield for almost any radiation, whether electromagnetic or nuclear.
Precisedly. Any container that is opaque to X-rays will be deemed suspicious and stopped.
Then they will be stopping every single car that goes through. I doubt it. I'm guessing it will be ignored if that's the only thing that looks strange.
My mom's a bit paranoid. She's very creative, but like me, it can make her look really crazy as she goes down the list of things she honestly considers possible.
Doesn't sound so bad. Most people look downright insane when you start asking them if they believe certain things are possible.
