My job includes electronic security & surveillance. It is true that there are a lot previously unbelievable gadgets out there being used to watch folks.
But, BUT...it's only useful if YOU are being targeted. Are you a spy? Are you dealing in something illegal that is worth a lot of $$$$$$$$ ? You could be flagged for further attention. Most likely, you'll still get away with it, tho'. Remember...we can't even catch Osama bin Laden. Or, the millions of aliens that 'land' without permission in America each year ? Then, there are the ones from Mexico, too.
Normal people just aren't on that expensive radar. Can you imagine how many people would be employed by the federal guv'ment...as lookers/listeners ?
We can't get thru (or call backs) to the SS Dept. because, they don't have enough money in their budget for more employees.
So, I suppose we can be glad the guv'ment is 'on the job'. They never get much done -- efficiently.
