The Trac Reports are out with statistics from March and David Burnham and Susan B. Long, co-directors at the Transactional Records Access Clearinghouse write that:

"Federal criminal prosecutions in March of 2007 jumped to 10,286 — 22% over the level in the previous month.  Fueling this monthly surge were large increases in immigration (up 17%), drug prosecutions (up 24%), and weapons (up 35%)."

And looking at the statistics for white collar crime, they were up this month see here and here. But they are still significantly down from a year ago, and even more-so from five years ago. (For a discussion of the February report see here).
