Wonder who the rat was. My guess is it may have been a Democrat politician who was involved with marijuana and who turned against Arenstein and/or his wife and stabbed him/them in the back.
The DC police don't seem to do much when Democrat bigwigs might be adversely impacted. Their failure to solve the Chandra Levy murder case for more than nine years and counting proves that.
BTW, Yedioth Ahronoth, the Israeli newspaper which employs Mrs. Arenstein, is a low-class tabloid.
. . .still trust nothing per first appearances - particularly, per Democrat Rule of Washington.
