I wish we could subscribe to a private peace force but government monopoly makes that impossible.
Think about this for a minute...
Back in the old days, there were private cops. They often beat up and robbed and/or flat out murdered dudes protected by the other cops, if you wanted them to actually DO something, you had to pay them more, and their charges were pretty much whatever they decided.
Would you like to go back to that? Having to be careful which part of the city you were in, whether or not your legal protection was valid at any given time due to time/date/service area?
You think the government fucks you over, wait till you see private peace force.
Compare the shit Blackwater and other merc groups pull to Britain, US, or Canadian forces, and you'll see what you get.
