"Evidence Laundering", "Parallel Construction" and the "Taint Review Team"

It's "a nice little plan to allow the NSA to illegally spy on people, tell law enforcement just enough to target people, without ever revealing how they were caught via unconstitutional means."

I'm sure "the road to hell is paved with good intentions." sounds better to the DEA than "the road to hell is paved in flagrant violations of the natural and constitutional rights of those whom you are chartered to protect."
