He did, the Patriot Act and the acts against American Citizens were both unconstitutional and wrong. His ignoring our Constitution and trying to bypass it by detaining people indefinitely without any charges is a violation of our Civil Liberties and illegal. I would have voted to impeach Bush based upon those issues. We fought a Revolution because of these issues, and we have several Presidents who ignore these principles in the United States Constitution. If we are not a country of laws, we become a lawless people.
This is not high crimes and misdemeanors. When we disagree with laws we need to be careful not to attribute The wrong kind of remedies.
Impeachment would be wrong even if Bush was wrong about this issue. Even if he is wrong it odes not reach the standard for impeachment. The push for impeachment seems to be more of a revenge tactic that a need for justice. The Patriot act as been to the courts numerous times.
