"greatly enhance intelligence and surveillance operations"
That they will, not a shred of doubt about that.
The only question that remains is : who decides what is a valid surveillance operation ?
Whatever the answer today, what happens when a new government takes power and decides to abuse the system ? People die, that's what.
Catching criminals is an essential endevour, but the potential for abuse - especially in the current state-sanctioned-universal-surveillance we currently live in - is enormous. Add to that we simply cannot trust politicians to not do it, and I think that this is, overall, a bad idea.
