Activists Use Laser Projectors to Warn Drivers of Checkpoints

Protesters are employing creative technologies in order to get their message seen. This now includes the use of laser message projectors that more effectively spread the message using bridges and buildings as projection screens. In the video, a group of New Hampshire checkpoint protestors illuminate a nearby overpass with the message “Police Checkpoint Ahead”. Absolutely spectacular!
