The year before the raid on Wright, a SWAT team from the Food and Drug Administration raided the farm of Dan Allgyer of Lancaster, Pa. His crime was shipping unpasteurized milk across state lines to a cooperative of young women with children in Washington, D.C., called Grass Fed on the Hill. Raw milk can be sold in Pennsylvania, but it is illegal to transport it across state lines. The raid forced Allgyer to close down his business.

Brian Walsh, a senior legal analyst with the Heritage Foundation, says it is inexplicable why so many federal agencies need to be battle-ready: “If these agencies occasionally have a legitimate need for force to execute a warrant, they should be required to call a real law-enforcement agency, one that has a better sense of perspective. The FBI, for example, can draw upon its vast experience to determine whether there is an actual need for a dozen SWAT agents.”

Since 9/11, the feds have issued a plethora of homeland-security grants that encourage local police departments to buy surplus military hardware and form their own SWAT units. By 2005, at least 80 percent of towns with a population between 25,000 and 50,000 people had their own SWAT team. The number of raids conducted by local police SWAT teams has gone from 3,000 a year in the 1980s to over 50,000 a year today.
