cops cant get away with enforcing unjust laws just because the law changes. future cops need to fear enforcing unjust laws because current cops were made example of.
when a law changes, cops who enforced the old laws become criminals. modern cops are domestic terrorists if you step back from it all and see the bigger picture.
it just takes one generation of cops getting punished for enforcing unjust laws, and you'll secure the future from tyranny for the next hundred years, because cops enforcing bad laws is required for tyranny to exist.
minimum 1 year prison sentence for anyone who has been in law enforcement the last 50 years, even old retired men. from there you can raise that time according to how many lives they've destroyed enforcing bad laws. police themselves know they deserve it, and have a lot of self hate for what they do for their paycheck. a large portion of them will take it willingly once they understand how it serves justice to punish them.
some prosecutors are some of the most evil men in our society and thy will not go down without a fight.
