As you have said....( I forgot that I had asked you your opinion before)..it is a very complicated question, and in some ways, even what the NSA has done up until now, may be not enough...if they aren't tapping domestic calls between terrorist cells within the USA borders...
However, on a purely political basis....what would these same critics be saying if this NSA program had NOT been started, or if they DID wait for warrants, and an attack had occurred before now...
Don't you think the "impeachment" talk would be even louder than it is for his doing it??
Part and parcel of "expecting pefection," pushing responsibility UP the ladder to the Federal Government, and a tacit PROMISE of "we'll do all we can to stop all the big attacks." See Katrina for a parallel. Thank God we don't get all the government we pay for.
