The problem with this mingling of domestic policing with military operations is that the two institutions have starkly different missions. The military\u2019s job is to annihilate a foreign enemy. Cops are charged with keeping the peace, and with protecting the constitutional rights of American citizens and residents. It\u2019s dangerous to conflate the two. As former Reagan administration official Lawrence Korb once put it, \u201cSoldiers are trained to vaporize, not Mirandize.\u201d That distinction is why the U.S. passed the Posse Comitatus Act more than 130 years ago, a law that explicitly forbids the use of military troops in domestic policing.<\/p><\/blockquote>\n
