Uh, perjury and conspiracy are, last I checked, real crimes. Here are a whole bunch of other real crimes too. If the point is one doesn't want Fitzgerald to bring difficult to prove and difficult to comprehend charges - an ambiguous perjury charge or a conspiracy charge which hangs on some slender reed of evidence - fine. But if people involved knowingly deceived investigators, and especially the grand jury, then they should do the time.
...and, let me add, the other reason to bring "non-central" charges in a case is to, you know, encourage people to cut deals and rat out the bigger fish so you can actually get to the central criminal act. This is something that people with crappy public defender representation (no offense to those good public defenders) deal with all the time. It's a part of our legal system which, whatever its merits, should surely apply to those with the best legal representation their money is buying.
