And they have extremely large case loads because Congress creates over 60 new federal crimes every year, and because the same prosecutors prosecute thousands of acts that harm nobody and should not be prosecuted. If they were made to actually work for prosecuting them, then maybe they would wake up to the reality of over-criminalization and asked for a reform. However, if they can just make a conveyor belt type system where they just can quickly extort plea bargains and move on, of course no problem for them.
I miscalculated the average a bit: it's 56.5 per year, not 60 (I thought it is 7 year period but it was 8 years).
The growth of federal crimes continues unabated. The increase of 452 over the eight-year period between 2000 and 2007 averages 56.5 crimes per year-roughly the same rate at which Congress created new crimes in the 1980s and 1990s.
