Your link spells it out. The 2 agents (Fina & Costanzo) claiming they were subject to intimidation (one of the charges against Kane) have a history of/long standing dispute with another agent (Miletto), i.e, departmental in-fighting going back to 2009, which evidenced itself yet again during Grand Jury hearings in an elevator snark session. That boils down to a "he said"/"he said" dispute. The far more serious charge against Kane is that she lied under oath, which goes to the underlying issues of first establishing there was a leak, and if so, by whom. All those matters can only be adjudicated at trial, where the defendant gets a full and fair opportunity to present evidence/defense. The burden in a criminal trial is to establish guilt beyond any reasonable doubt - a much higher burden of proof than in a civil trial.
By stripping her of her law license before any criminal conviction, the Supreme Court has truly denied her due process and the right to trial. I'm shocked by this. As your linked article also pointed out, actions by Kane's office led to one Supreme Court Justice resigning in disgrace.
Any lawyer will tell you, publicly criticize or challenge any judge, even mildly, at your own risk. Judges circle the wagons to protect their own, and they have long memories. They will get payback in future trials where that lawyer may come before them, as well as against other lawyers from the same firm as the critical lawyer.
I'm not claiming Kane is innocent of the charges brought against her, but there's a lot of politics involved in this case - and since Wolf has abandoned her (before any finding of guilt), she is on her own. It's very ugly.
