While being a bad lawyer isn't a crime, breaking laws in an effort to help your client certainly is, and there is plenty of legal precedent to prove it. Defending Trump through legal means would be one thing, but helping a sitting president to line up fake electors — as it appears both Eastman and Giuliani did — is engaging in a criminal scheme not protected by attorney-client privilege. These defendants are guilty of the same things Trump did, which is why the justice system is doing its job and leaving no stone unturned.
Besides the obvious political nature of this case — a partisan Democrat District Attorney (DA) prosecuting a Republican presidential candidate — Fulton County DA Fanni Willis is wrongly charging these defendants as a "criminal organization." This is nonsense, as these individuals were never part of the same organization. If Willis couldn't find solid evidence of an overarching conspiracy — and her definition of an "organization" is slippery — it seems this case can't go very far if conducted in a fair and balanced manner.
