This is not a good trend:
Radley Balko: SWAT Raids, Stun Guns, And Pepper Spray: Why The Government Is Ramping Up The Use Of Force: According to Eastern Kentucky University criminologist Peter Kraska, the number of SWAT raids carried out each year in America has jumped dramatically over the last generation or so, from just a few thousand in the 1980s to around 50,000 by the mid-2000s, when Kraska stopped his survey. He found that the vast majority of the increase is attributable to the drug war -- namely warrant service on low-to-mid-level drug offenders. A number of federal policies have driven the trend, including offering domestic police departments military training, allowing training with military organizations, using "troops-to-cops" programs and offering surplus military equipment and weaponry to domestic police police departments for free or at major discounts. There has also been a constant barrage of martial rhetoric from politicians and policymakers.
