And someone in the NSA or DHS, drops a phone call to the DEA and says "hey, check out these 2 guys." I have a SERIOUS problem with that, because that information was obtained in violation of both citizens inalienable rights, and it was obtained WITHOUT a warrant and under the GUISE of looking for terrorists. 
I can easily see the system of warrantless wiretapping being abused in this way. And, we would have absolutely NO DOCUMENTED WAY to verify if such action had occured. It also brings such a huge temptation to agencies like the DEA, FBI, and ATF who need big busts to justify their big budgets, to call down to NSA & DHS and say "hey, look for these key words, thanks!" 
You can attack my argument as purely hypothetical rhetoric, however you cant really deny that it is very possible and I would argue LIKELY, that the system would be abused in such a manner.
