A woman driving to work on Sept. 4 saw an ICE raid underway in Dover, N.J., and followed the vehicle carrying detained people up Route 46 toward the Roxbury warehouse, recording video along the way. She said a white Dodge Durango and then a black Tahoe began circling and filming her on a public sidewalk, which she described as intimidating. She asked that her name not be used, saying she fears what the government might do.
