ICE arrested a witness at the Minnehaha County Courthouse in Sioux Falls while the person was testifying in a trial. The arrest occurred in front of the witness's wife and baby while jurors were on break. The judge immediately declared a mistrial. The Public Defender's Office noted that the witness had been legally subpoenaed and that the defendant is a U.S. citizen, expressing concern that such arrests could deter witnesses from testifying in future cases, particularly in immigrant communities.
