I agree with the above post. Criminal Justice degrees are a cakewalk.
Other than the fact too, if you apply for police work with a different
degree, then you will be more marketable since this will set you apart
from applicants with CJ degree. Remember that police departments
want diversity.
Finally, the last reason why you should go for a different degree is
because in the case that you don't get hired as a PO, you can still
work in a different industry.
There is just so much you can do with CJ degree -- police officer,
security guard, probation officer, etc., but that's about it.
The best degrees IMO are IT, computer engineering, computer
science, business, and finance.
