Technically.  Apparently he liked to write letters of reccomendation with the names left blank and sell them to filthy xenos.  Chances are, the profits were used to finance some of his back end dealings, of which he had quite a few, none of which could ever quite be traced.<br/><br/>In general, my portrayal of the Imperium of Man assumes that the system is broken, and anyone who gets things done gets it done either by being so absurdly high ranking that they can singlehandedly doom entire worlds, or because they commit insane amounts of treason and small amounts of heresy on the side.  Krozer is one of the corrupt ones, but since he tends to act ultimately in defense of Mankind, the Inquisition has little interest in him.<br/><br/>(For the record, insane levels of corruption is also why the bureaucracy doesn't tend to work, because half the levels of the administratum are run by bribes and assassinations, and the other half are either fanatics who wouldn't douse themselves if they were on fire unless the proper authorization forms were filled out in triplicate, or servitors with no higher brain functions.  Often, it's a combination of these factors combined with a heretical or broken central cogitator core that turns any particular section of the Imperium into a hellhole.  The Inquisition and the Adeptus Arbites keep things to a reasonable level, but they have limited resources, and in the case of the Arbites, limited jurisdiction.  Naturally, the fact that the Imperium of man actually manages to survive in spite of how completely broken it is only makes rebellion against it more ironic and hopeless, since it would seem like the only people in the entire Imperium who even believe in what they fight for are the Space Marines.)
