IMTU stuff on imperial crimes: my conception is that not all of these are crimes that the imperium normally tries or prosecutes, rather they are activities that the imperium insists be illegal on all member worlds.
As somebody pointed out in the 1248 forum recently, murder may be an imperial high crime but it's not likely that the imperium handles all murder trials. There are too many. It insists that murder be illegal on member worlds, though, and it perhaps can get involved if it chooses to.
Semi-relevant example: the US federal government doesn't handle murder trials, they're the business of the states, but it did get involved in the Rodney King affair after public opinion found the state's handling of the matter unsatisfactory. As I recall the US goverment used civil rights laws (rather than murder laws), but the imperial legal framewrok might allow more direct overrides.
The imperium will tend to get more directly involved when it's something out of the ordinary (WMD vs cities) or of a fundamentally interstellar nature (trade, smuggling).
