Federal defendants take plea deals because 1. their resources to fight may be not be close to what it will take to defend a complex case through the trial phase, and 2. they are looking at dozens of years or longer without the possibility of parole, and a deal gets offered because they are a small fish and the case doesn't really have legs. It costs a small fortune to defend white collar criminal cases through trial.
In Miami or Ft Lauderdale, Kriisa may not have even been charged, because there are just too many other big fish out there to prosecute. In West Virginia, a case in the 2M range gets attention.
