Or other jobs such as TSA? A distant uncle of mine who is a police commander in Wisconsin told me if I wanted a Fed job, I should start with something like TSA,
My ex girlfriend is TSA. I met a lot of people through her that jumped into TSA with the same idea as what your uncle suggested.
The nicest way I can put this is that I think you would be really unhappy with the job and the people if you decide to be TSA for a little while.
