Botched Paramilitary Police Raids
This Google Map from the Cato Institute shows the location of botched SWAT and paramilitary police raids in the United States.
The Cato Institute argue that "the Drug War (has) 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."
The map uses coloured map markers to show raids that led to the death of innocent people, the death of a non-violent offender, the death or injury of a police officer etc. It is possible to refine the data on the map by state, year and by outcome.
