There's a big difference between * criminal justice (where you mete out punishment, and want to act only against confirmed bad people (and in case of doubt, you don't act), and therefore you require very strong evidence against someone), and * examining candidates for one of the most elevated positions in government (where you hand out power, and want to appoint only confirmed good people (and in case of doubt, you don't appoint), so fairly weak evidence against someone is enough.) That's not really a particularly hard distinction to grasp.
