I had to spend money to sue the local unemployment office because a bureaucrat there illegally cut off my unemployment payments. They lost and had to pay me back in arrears but that money came from the taxpayers(so me and you) and that asshole who did that is still working there just fine collection golden handcuff paychecks and a gold plated pension when she retires.
All civil servants need a form of direct accountability with consequences for their mistakes at work, especially when malicious and repeated. Currently they're untouchable and the taxpayer foots the bill for their mistakes with no repercussion.
If supressing cases or throwing big money lawyers against legitimate lawsuits is cheaper, they will do it. If teaching cops to hide their corruption is easier than rooting out all the corrupt individuals to raise rates, thats what they will do.
