Yes you can and you should. You like too many others are happy to sit idly by and watch the decay of society but some people actually have ethics and care more about keeping the community safe over “muh private property”.
And a lot of people think they have the correct ethics and idea of what is needed to keep communities safe, and believe they should be able to take the law into their own hands. I don't know if you'd be very happy with the outcome of everybody actually doing that.
I'm going to rip it off, doing my civil duty, right? Not like there are any laws preventing me from doing it it.
Get off your high horse.
