This is a much more interesting question than the one that usually gets asked, IMO.
I'd be okay with mass collection of metadata, as long as searches through that data had to be limited, audited, and focused on a specific topic for a specific active investigation. And if there were a trustworthy access control and auditing process to make sure there were no more LOVINT leaks, and none of that bullshit that the FBI pulled on MLK jr.
However, I don't think I would trust any agency to not find a way around that, in time. The power is too great, it's too tempting, and administrations change. Therefore, in our real world, I don't support mass un-targeted perpetual data collection, at all.
