For a shocking glimpse of what’s been happening in the name of criminal justice in America, look no further than a Justice Department report last week on police behavior in Louisiana. Officers there have routinely arrested hundreds of citizens annually without probable cause, strip-searching them and denying them contact with their family and lawyers for days — all in an unconstitutional attempt to force cooperation with detectives who finally admitted they were operating on a mere “hunch” or “feeling.”

This wholesale violation of the Constitution’s protection against unlawful search and seizure by the police in Evangeline Parish, including in its largest city, Ville Platte, was standard procedure for putting pressure on citizens who the police thought might have information about crimes, according to the findings of a 20-month federal investigation. The report described as “staggering” the number of people who were “commonly detained for 72 hours or more” with no opportunity to contest their arrest, in what the police euphemistically termed “investigative holds.”

The sheriff’s office in Evangeline, with a population of 33,578, initiated over 200 such arrest-and-grilling sessions between 2012 and 2014. In Ville Platte, which has 7,303 residents, the local police department used the practice more than 700 times during the same years. The residents faced demands for information, the report said, “under threat of continued wrongful incarceration,” resulting in what may have been false confessions and improper convictions.
