This spying is absolutely necessary and we must use every weapon we can against the terrorists who would harm us.
That said, the potential for abuse of the type liberals are worried about does exist -- not so much under this administration, but perhaps under the next one. Soem monitoring and oversight, perhaps an explicit laying out of the circumstances in which this power can and cannot be used, may be appropriate, to allow this necessary function to go forward while at the same time rieining in the potential for abuse.
agreed. While the spying a crucial element of the anti-terrorist fight, you're absolutely right that the possibility of corruption and tyranny are there...but they always are. We will always need to guard againt politicians who would use government power for their own benefit.
