Just read a story in The Economist citing a study in GB that money spent for private police protection was 5 times (?) more efficient than the money spent on public policing. Their observation was that the primary cost savings was in wages and benefits. I suspect that in the US the same cost savings would hold true. But Sir Bobby Peel invented the Metro Police because at that time it was an efficient use of public funds. What changed? 30 years ago I read that in the US more money is spent on private security measures that the total of all government police agencies and I suspect that is still true. Say local and county police agencies were cancelled. The real estate tax rate around here would drop maybe 25% if the jail was included. Could the jail be included? How would it effect the operation of the court system? How would the neighborhoods change?
