I think Franklin thought himself up a clever slogan, one which he would certainly reverse were he alive today.
Our homeland has been attacked and has been threatened with further attack. Those who would insist on some total right to privacy in their dealings with foreign enemies, real and potential, are guilty of one of two things:
1. Either they hope America's enemies are successful or
2. They are blind to the fact that they are trading security for a liberty that will only be temporary.
Again, where do you draw the line? What is NOT an acceptable limit on government surveillance? Anything at all?
Do you think that the founders would change their position on absolute firearm rights if they saw what sort of weapons are made possible with modern technology?
