UPDATE: Drug War Chronicle story about this incident online now. We wrote about police harassment of attendees at the Wakarusa Music and Camping Festival when the event occurred in June, but little did we know that was only the tip of the iceberg. Now, thanks to the bragadoccio of a high-tech surveillance equipment manufacturer and a resultant puff piece in an industry rag, we know that state, local, and federal law enforcement officials were all on hand at Wakarusa to check out a demo of some very sophisticated surveillance equipment. With hidden cameras, night vision equipment, and thermal imaging, cops were able to surveil up to 85% of the festival grounds, spot drugs and money changing hands, watch people roll joints, and subsequently make arrests.
