During my time as an intern at the Loudoun County Sheriff's Office I got to experience the day to day life of law enforcement officers and those who serve in unsworn administration positions. I liked being able to gain respect for everyone that serves in a local law enforcement capacity.
What I wish was different
My advice would be to do research before applying to an internship no matter what it is, but specifically one where you will see people at their worst. Be sure that it is something you really want to do before applying.
