I agree that you should never open your door to the police. NEVER. If they then have that actual warrant, not opening the door isn't going to stop them.
In your scenario, you've left your fate of being unlawfully arrested in the hands of the very government that unlawfully arrested you.........how sensical is that? yes, you're alive, but maybe that judge loves cops, so he absolves them of any wrongdoing. Now you're in jail to stay, even though your rights were clearly violated. On the off chance that qualified immunity is overcome and you can actually sue those individual officers, they suffer no punishment. The entity that employed them pays insurance premiums, that YOU paid for through taxes, to cover any settlement awards or damages awarded by a jury. If, for some reason, they end up being shown that they were in the wrong, their union contract allows them to resign in leiu of being fired, saving their years for pension, and they just end up hired by another agency............or as a complete fuck you to the public, and you who were wronged, those officers stay hired and get promoted.
it's a shit show where the people are only offered the illusion of maintaining power, where they actually have none.
