Why crucify the lawyer?
In order for someone to be punished in a just society, they need to have a trial.
In order for that trial to also be just, both sides need to be able to put forth their side of what happened.
In order to make sure that there isn't a mistrial, both sides need competent lawyers, and the case needs a competent judge.
The alternative is that that police can just target people they don't like, knowing that they likely can't defence themselves, even if they are innocent.
