The Cato Institute has an interactive Google map of botched police raids. Most shocking is the number of innocent people who have been killed across the country by inappropriate police raids. Clicking on map locations gives you more information and links relating to the particular incidents.
The proliferation of SWAT teams, police militarization, and the Drug War have given rise to a dramatic increase in the number of “no-knock” or “quick-knock” raids on suspected drug offenders. Because these raids are often conducted based on tips from notoriously unreliable confidential informants, police sometimes conduct SWAT-style raids on the wrong home, or on the homes of nonviolent, misdemeanor drug users. Such highly-volatile, overly confrontational tactics are bad enough when no one is hurt — it’s difficult to imagine the terror an innocent suspect or family faces when a SWAT team mistakenly breaks down their door in the middle of the night.
