Police can traipse onto the vast majority of private property in the country without a warrant thanks to a century-old Supreme Court decision, according to a new study by the Institute for Justice, a libertarian-leaning public-interest law firm.
In a study published in the spring 2024 issue of Regulation, a publication of the Cato Institute, Institute for Justice attorney Josh Windham and research analyst David Warren estimate that at least 96 percent of all private land in the country is excluded from Fourth Amendment's warrant requirement under the "open-fields doctrine," which allows police to forego warrants when they searched fields, woods, vacant lots, and other property not near a dwelling.
