The charges against Alec Baldwin got dismissed with prejudice (they can't be brought again). The judge said the prosecution did not provide evidence to the defense.
This entire prosecution was a shitshow from day one. The gun was broken in testing. The initial charges were dropped and then brought again. The first prosecutor resigned due to conflicts of interest. In this trial another one of the prosecutors resigned and another prosecutor took the stand.
The saddest thing is that due to both malice and utter incompetence, shit 100 times worse than this is routinely done by prosecutors in criminal cases and they almost always get away with it because the defendants are impoverished and public defenders are so overworked and underfunded it's a miracle they all haven't snapped, and because we as a society generally treat any marginalized person accused of a crime with seething contempt and scorn and we're fine with prosecutors doing sleazy unethical shit when they already have a stacked deck to throw people to the carceral wolves to be ground into dust by the American prison industrial complex.
