In Need of a Hero

Our society is in dire need of a hero. Not a political hero, a hero that  is sworn to physically protect US citizens because it's obvious that the police aren't exactly enough to protect the people of the United States. Actually, it would be a lot better to have different factions of heroes: Some for political purposes and some for the protection of the people. The United states needs help and there have to be people that are either willing to stand up to help or let themselves do what they feel is right.
What our heroes would need are determination to keep doing what they can do to help people regardless of their own feelings or stress. They need to put others before themselves and think about the benefits of the people. The most important thing they would need is the willingness to sacrifice something of theirs in order to help others. What they sacrifice can be as small as energy to do something  or as big as their own life. The heroes don't need to have any powers, they just need to have what it takes to help others and get others to help themselves as well as those around them.
