You dont need LE experience thats what an aademy is for ( or at least thats what they tell you my learning was all field training.) Every job you hold is important for the application and interview process.
Every retail or fast food job teaches you to deal with a number of different types of people which can be helpful. Best thing you can do wheh nyou graduate is apply but while waiting get a job and keep it! long history does help. Going from job to job isnt a huge deal when your in college provided you left them on good terms.
