That might be true if the police were ever designed to actually "protect and serve" and their purpose was being twisted, but they've always existed only to serve the rich and protect their property, nothing more.
Bottom line - be frustrated with them all, judges and politicians (and the ultra rich who own them), and the police, since they essentially serve to uphold each other.
If voting actually changed anything, they wouldn't let us do it.
Now I'm don't saying don't, I'm saying it's bare minimum (and that a protest vote still counts, in the UK at least, so you don't have to actually choose a clown, to participate), and at best is going to change the puppet in charge, but never the theatre we're in, they designed it that way and have only ever given us the illusion of choice.
The whole lot is a cancer and needs to be abolished - capitalism, 2 party "democracy", the police and "justice" system that serve both, and in our case the cherry on top - royalty, aristocracy, and gentry. Those profiting and otherwise benefiting from those systems are never just going to give it all up and hand over equality to us, they will, and pretty much are, take humanity down with them before giving up their positions of power. There is no loophole, they have not provided a way within the system for us to free ourselves, if only we just do the right voting combo. The whole thing is rigged to keep us always fighting for survival while they reap the rewards.
Instead of continuing to play by their rules, the working class need to build our communities up (with things like community kitchens, communal childcare, "libraries" for all sorts of household objects, and so on and so on, to make sure no one is in need), foster solidarity to combat the division they sow to keep us weak, and unite to be the force for them to reckon with we always have been.
E: LMFAO at a person who uses Jesus in their name downvoting this, as if it isn't exactly what Jesus taught.. 😂
