Wyatt Earp

I have started reading a book called Wyatt Earp. It is about a cowboy who becomes a sheriff. The reason he becomes a sheriff is he is very good at bringing criminals to justice without using a gun. In the book,  bunch of cowboys start riding into the town to kill people. Then Wyatt grabs a shotgun and stands in the road in front of the cowboys. Then one of the cowboys yells, "It's Wyatt Earp!" Then they all ride away.
