Kindness is an admirable trait in a lawman, but it must be tempered with a healthy dose of suspicion. It was a lesson U.S. Marshal Hal Gosling learned too late. His good nature led to his death, setting events in motion that would break up of one of the worst outlaw gangs to plague south Texas in the 1880s.
You can read about Marshal Gosling’s sad demise, and the end of the Helotes Gang, in my article from the December 2013 issue of Wild West Magazine, recently put online at Historynet. For a fuller account, see Chapter 3 of my book, Some Gave All.
