Having a Fed-ex can be a real double-edged sword --- on da one hand, if you
two parted ways amicably, he might be willing to "pull some strings" wif
da higher
government mucky-mucks on your behalf. But on
da other hand, if said breakup was NOT overly pleasant, it could mean dat said stuffed-shirt intel-rep could very likely possess certain knowledge and/or power dat he could use to "make things warm for you".
P.S. A third situation could also be
da case if said former
heart-throb is now actually an "ex-Fed" --- as in, he's no longer working a government
job. Depending on which fellow-officials he knew during his employment and/or why his "lofty" position was terminated, he might or night not still have significant "pull" wif his cronies in Washington, and thus his "heat-creating" powers over you could vary greatly.
