suspension of 1st amendment was considered by bush regime

[El Blanco]

While I disagree with such measures, they are hardly unprecedented. Saints Roosevelt and Kennedy played pretty fast and loose with the Constitution. As did Jefferson, Wilson, Lincoln etc etc.

I guess it all depends on just how much of a threat we face and how effective such measures will be.

And I also don't see where it says these memos were actually going to be made policy. Presidents put together groups of advisers and want every option and its outlook. That doesn't mean these ideas are going to be put into place. The most famous of these would be Operation Northwoods.
