Maine ranks #1 for Fourth Amendment freedom, scoring 9.5/10 — typically a state that requires a criminal conviction before forfeiture and routes proceeds away from the seizing agency. The full ranking is above.
A handful of states now require a criminal conviction (effectively ending civil forfeiture) and close the federal "equitable sharing" loophole. Those states score highest here; states with low evidentiary bars and a profit incentive rank lowest.
Massachusetts ranks at the bottom of the Fourth Amendment list, reflecting weak forfeiture protections and a profit incentive for seizing agencies, alongside thinner digital-privacy and surveillance safeguards.
The Fourth Amendment score draws on the Institute for Justice’s Policing for Profit forfeiture grades plus state digital-privacy and surveillance laws. See the methodology page for sources.
