Here's the thing -- that's the defense lawyer's job.
The job of the prosecution is supposed to be to find the truth; but, most of them see the goal of their jobs as to accumulate convictions. The job of the defense lawyer is to serve the client, and get the best possible outcome.
Of course Baldwin's lawyers are making bad arguments. He gave them an impossible set of facts, and compounded that by talking to the police without a lawyer.
We know that he knew that he was operating a real gun -- by his own words. We know that he knows not to point a real gun at another person -- by his own words. We know that he neglected to check the gun himself -- by his own words. We know that he knows how dangerous guns are -- by the last several decades of his words and actions with gun control activism.
We know that the gun didn't malfunction -- by the findings of the FBI. We know that guns like that don't fire without fully cocking the hammer and pulling the trigger -- anybody with questions about that is welcome to examine my own Colt revolver.
They're defending a guilty client; so, they're grasping at any straws they can find.
Prosecutors do the same thing. The state made a plethora of dumb arguments in the Rittenhouse case, because they were trying to convict an innocent person.
The moral difference is that the defense lawyers are doing their jobs properly, while these activists prosecutors like Binger are violating the basic ethics of their jobs.
