Some questions I'd like answered regarding the NSA and their spying on ordinary Americans

"If tyranny and oppression come to this land, it will be in the guise of fighting a foreign enemy" - James Madison 

In his book, A Time for Truth, William Simon (Nixon's Treasury Secretary) wrote about freedom when describing his trip to the old Soviet Union, saying that while they were never directly bothered by anyone there, they were aware of being under constant observation. It was on the flight back to the U.S. that he gained a true understanding of the nature of freedom: when the pilot announced they had left Soviet air space, everyone visibly relaxed. Simon wrote that it was at that moment that he realized that it's easy to take freedom for granted because it isn't a presence in our lives, but an absence. 

Here are some questions I'd like answered regarding the NSA and the new revelations of their breaking thousands of laws and spying on ordinary Americans: 

• Why wasn't the NSA with all their data mining about to detect and prevent the Boston massacre? They even had explicit warnings from the Russians.
• Why was the NSA was not able to stop the Maj. Nidal Hassan from committing his jihad slaughter of 13 individuals at Ft. Hood along with 33 who were injured? We had ample evidence of his radical Islamic beliefs several years earlier and didn't need any data mining to discover that he was becoming radicalized.
• Where is there any real accountability with the NSA? Security agencies like the NSA define their own legal standards and have no real accountability. 
• Where is the judge who rules on these privacy invasions? 
• Where is the court where an ordinary citizen like myself can appeal this personal intrusions? What mechanism ever informs an individual that his rights have been violated?
• How can we trust those who are in charge of our national intelligence when the director of national intelligence lied to the American people with no consequences? If we lie to the federal government under oath, we face imprisonment.
• Explain why phone records of the 202 area code were mistaken for the dialing code of Egypt, (20)? Why was the 202 area code even available for such an error. This is a database query, so the records had to be in the database to query them. Which means that somebody, somewhere, thought that they should be or thought that they should not have been excluded from the collection.
• Why should we believe anyone in this administration or those heading up the NSA or national intelligence when thus far, they have lied to us on numerous occasions and proven to be less than truthful in the scope and amount of data being searched?
• President Obama assures the American people that there is no evidence of this data being abused or misused against the American people. In light of the IRS going after Tea Party groups, and the Justice Dept. going after Fox reporter, James Rosen, why should we not believe that this information could be used against any American to destroy their life or put them in jail just because they are opposed to this administration?
