If politicians can't be trusted to interfere with the judiciary, then it's the best of a bad situation.
Dude, what planet are you from?
Judges, prosecutors and lawyers has always been the most hermetic corporation with it's root going deep into communist times.
And right now there's absolutely zero public control over what happens in judiciary branch of the state.
Jan Bury (an obvious crook) was able to be a member of Krajowa Rada Sądownictwa (office meant to control courts) for how many years exactly? And why nothing could have been done against him, even though there was a mountain of evidence collected? Why a judge didn't allow for him to be arrested?
Because it's one big "I scratch your back, you scratch mine" buddy-buddy system of corruption.
