I would be outraged if they didn't do stuff like this!
Am sure hoping Sam Alito gets confirmed soon and good sense returns to the highest courts in the land!
This type of nuclear monitoring has been going on for at least 40 years.
I saw a film clip on TV of a person dressed in a business suit carrying a brief case going into the NY subway;and later they showed him walking by buildings etc.
Then they explained he had a Geiger counter type of device in the suitcase which would show if there was any nuclear device nearby.
I remember being upset they let this info out; because a bomber who saw it would just keep the nuclear device out in the countryside until boom day. - Tom
