By the time the caravan had reached Seattle the threat of violence was constant. All week, talk radio hosts, both in the Northwest and on national broadcasts, implored their listeners to confront the Reform Riders to “show Hillary” their feelings about her. This "call to arms," as she described it, attracted menacing hordes, many of whom identified themselves as militia members, tax resisters and anti-abortion militants. She estimated that at least half of the 4,500 people in the audience of her Seattle speech were protesters. She agreed for the first time to wear a bulletproof vest. Rarely had she felt endangered, but this was different. During her speech, the catcalls, screaming, and heckling drowned out much of her remarks. When she left the stage and got into a limousine, hundreds of protesters surrounded the car. They were rabid with hatred. Several arrests were made by the Secret Service, which impounded two guns and a knife.
