I not so sure that it isn't a word problem at work here.
For years now we have stated many domestic problems and issues in words that have to do with war and fighting: war on poverty, war on drugs, war on crime, and now the war on terrorism. The foot soldiers in all these wars are mostly the police. Yet we send the army out on peacekeeping missions. It can become confusing. The police used to be called peace officers and the army had soldiers. It leads to the wrong idea in many people's heads.
Likewise, why do the police, especially the state police, go in for what used to be called a Prussian haircut. Are we about to criminalize hair? Is this something left over from the late 1960's? I won't even ask about shaved heads. What else do people shave?
And then there are the SWAT units. I think that sometimes the presence of such things creates situations where they are required. In other words, they will be used whether or not they are necessary because they are there to be used.
There are bigger issues that I am alluding to, perhaps, like permanent war. After all, it is to the government's advantage to have emergencies because that is an excuse for emergency powers. But maybe I am thinking only the worst about government (not THE government, just government generally, everywhere).
