Navy vet beaten by federal agents: 'They came out to fight'

Under the assault, 53-year-old Christopher David seems like a redwood tree — impervious to the blows. Militarized officers from a handful of agencies have been using tear gas, flash-bangs, pepper spray, “less-lethal” impact weapons and other munitions to disperse crowds. The U.S. Department of Homeland Security, which has deployed officers to Portland, did not immediately respond to a request for comment on the incident that David recounted.
