Just like any other job, law enforcement is not a career suitable for every person.
Quite contrary, taking a law enforcement degree requires more than just being an intellectual.
The job of this person, once he/she gets a degree will be dealing with people most of the time, meaning that he/she needs to possess exceptional communication skills and be calm and stable so as to avoid a fight, using force as a last resort.
These professionals will be assessing, interviewing, and resolving conflicts, so mental and health fitness are the attributes to consider.
Furthermore, the physical workout is a necessity and the development of a strong mental habit, especially in pursuit of a criminal investigation with less sleep, is a must.
