A key point is that the Navy does not have to disclose the details of the DFC. Sometimes, when a CO is still 'under investigation' it's because everyone knows the allegations are true (by everyone I mean the junior enlisted ranks on the ship), but the NJP process has to catch up. Typically these are in the 'don't dip your pen in company ink' category.The policy is to publicly disclose DFC for COs. Whether that’s humiliating or not depends on what that particular CO has done.
