Veteran US Senator Dianne Feinstein probably never knew what it was like to be spied on until now.

US Senator Dianne Feinstein

Since last June's exposure of the National Security Agency's rampant surveillance scandals, the chairwoman of the Senate Intelligence Committee has been a staunch defender of those surveillance programs, despite the fact that these programs have drawn sharp criticism and protests from both US citizens and people in nations around the world.

However, on Tuesday, Feinstein seemed somehow connected with the majority of people in the world, when she lashed out at the Central Intelligence Agency's spying on the Senate Intelligence Committee's staff and computers. She accused the CIA of trying to undermine the committee's work on an investigation report regarding the CIA's illegal torture and rendition programs following the Sept 11 attacks on the US in 2001.

Feinstein said that the CIA spying had broken the law and even violated the separation of power principles embodied in the US Constitution.

The courage demonstrated by Feinstein, a Democrat from California and a supporter of US President Barack Obama, should be applauded, but the 80-year-old may not have changed her mind as much as people think.

Feinstein is deeply concerned about CIA's spying on lawmakers, but she has not said it is wrong for the agency, and the NSA, to spy on ordinary people all over the world.

If US lawmakers' right to privacy is important, what about the privacy of ordinary US citizens and citizens in other nations, especially those which are not allies with the United States?

Sadly, most conversations in the US are about how wrong it is for NSA to spy on US citizens, few seem to care to what extent the NSA is conducting its invasive surveillance outside the US.
