However, Scott Olsen was among those who disposed of their medals according to reports I have read. He belongs to the very well-known organization that all the other vets who were there, belong to. Veterans were among the first supporters of this movement. Most have provided their information, which they must do anyhow, to the organization they belong to.
Otoh, I would not be surprised if someone posed as a veteran in an effort to discredit both the organization and the movement. It happened several years ago. Mostly to do that would be someone from the far right.
As for the headline, the Vets are not responsible for what a news paper writes. I did not hear any of them call themselves heroes.
But reading the vile comments attached to news articles about their decision, it is clear that it does take moral courage to be able to stand up and tell the truth, especially knowing the vilification they will receive, and have today, from the far right.
And because, to have to admit that they participated in something they know now was so wrong, is a difficult thing to do. Remember Kerry did this, and today, so many years later, he is still being smeared by the Right for his actions. These men know, as threatened today by members of the far right, that if they ever run for public office eg, this will be used against them. It is a big decision and it does take a lot of moral courage to do it. And I doubt any of them care about being called heroes, or have referred to themselves as such.
