Not arguing for star courts. The UCMJ is a supplement to civilian courts, but applies additional levers. I am arguing that a similar system be applied to federal LEO. Right now they are only beholden to the civilian system. How is that going? Even if the administration prosecuted ICE for murder, it'd just get chucked out of federal court. All the 'officer' would have to do is not enter the state again.
I'm taking a charitable interpretation of your take for sure. I do see the value of additional levers, but I don't think realistically it would be feasible to make such a court.
Counter-point: I don't think Chauvin would've been brought to justice if he were tried in some kind of cop-court.
I'm open minded though, I appreciate your perspective, gave me food for thought.
