Perhaps interesting because as a society we pay a shocking lot for measures we are told are to do with dealing crime blows. We pay, more than for universities, towards keeping other humans locked as they are dangerous, pay for police and judicial systems, we pay for politicians to help keep us poor lot safe from one another (..and poorer..), we pay for the resulting hierarchies, and pay for paying by considering a numerical economic systems essential – which kind of helps some people consider transgressing despite then becoming, err, criminals..?
