What is a good college major to fall back on, if law enforcement does not work out?

I'm looking into some federal law enforcement groups in Homeland Security such as Immigration and custom enforcement, federal protective service, U.S. Marshals, etc. At first I wanted to go for criminal justice and figured if this doesn't work out I can't really do anything else with criminal justice than law enforcement can I? The reason I listed so many in(federal?) law enforcement you tend to move around and change jobs quickly and there's many to chose but what if law enforcement isn't for me? Most law enforcement require a 4 year degree which isn't limited to criminal justice so I might as well get another degree that will open up way more job options.
