The traffic statistic is a bit tired--but it is 43k---nonviolent occupants of federal in federal prisoner 1.5 m--when the unemployment rate falls below 4%..~3M..we get concerned because the labor market might be over heating--so, as you consider strategic parameters the first thing I think you need to do is establish a meaningful threshold for the number of people that we care about---not as indivuals--but as a national asset or resource. When we were looking at AT for ships, it became obvious--not accepted just obvious---that it was important to protect to protect the capability of the battle group, not the individuals or individuals assets in it--so, you could lose a frigate but not a carrier---you could lose twenty bosun's but not twenty pilots--so you could set strategic parameters of what needed to be protected, why and at what cost---when you expand that process to the nation--the numbers become huge--and as a result, you never try to protect 100, 1000 or 10,000 people--which, allows you to avoid problems like shooting bipolar people in airports, saves a lot of money etc----within a strategic framework, it makes perfect logic and good sense to set acceptable casualties in line with other, already accepted, amounts
