i had/have mixed feelings about all this stuff. we really did need to update the laws to reflect new tech. this update is not unregulated, but any time the government can get into your stuff, you have a risk.
it appears to me, not being a lawyer, but having read the laws as they were developed and the following court cases, that this gathering of info was done outside the scope of the laws. i also wonder what kind of an expectation of privacy the courts will find that we have, when we are using so much tech that is stored in the cloud, transmitted wirelessly, etc. it will be interesting to find out.
to be honest, i am less fussed about a mass gathering of stored data than i am about the IRS being used as a weapon against certain people, or that the government sat by and watched our people die so as not to disturbed a template or our "friends". those are both moral failings, where the gathering of my tea cake recipe and a call the my sister overseas, are not.
