If the government does not meet that expectation, it is time to hold politicians (and, where applicable, the police administration) accountable by voting them out.
It's a noble ideal but we're still not there yet so you can either shout at the Universe demanding it to be fair, or you can to try and live with what we have right now.
I do expect the roads to have no potholes, and car drivers vigilant but I still look where I put my feet when I walk and look the street both ways before crossing it. When I trip on something because I was distracted I first think "Who the hell put that there?", then "Probably should have watched where I was going" second. Am I subconsciously trained to victim-blame myself?

One of the reason for "criminal careers" is that convictions - especially those for small scale shit like fare dodging or marijuana smoking - follow people around and make it impossible for them to obtain housing and employment. Break that cycle and help people who are in prison to live a crime-free life after release, and crime numbers will drop.
