Before you tar & feather me for pokin' a hornets nest; I have never asked/addressed this question with any agency or LEO, and don't intend to. I just ran across the article/letter, while surfing the net! I pretty much agree with you. If you don't ask, they (probably) can't say no.
I just put this up so everyone could read it, as it was the first time I had run across anything, in print, from the feds.
