I want to know the answer to the following question:
How many vets participated in the protest?
All the background I'm provided with is that "The day after this testimony, Kerry participated in a demonstration with thousands of other veterans in which he and other Vietnam War veterans threw their medals and service ribbons over a fence erected at the front steps of the United States Capitol building to dramatize their opposition to the war.". Is that enough to answer the question?
Answer: no
