Ken,
I fully accept terrorist catching is dirty work etc, but profoundly disagree that 'Cops are instrinsically unable to do these things'. Or do you mean only in the USA?
Before the 'new age of terrorism' there were many examples where CT campaigns succeeded, for example one booklet cited Italy, Germany, France and Spain. In all of them the police were the main player IMHO.
Leaving prevention aside for now, a lot depends on whether your strategy involves criminalisation and so the need for evidence to present in court.
