Do a project on finding out when CJ programs require their students to have eye exams. I'm in optometry school now and we see a lot of senior CJ students coming over for eye exams and there is usually a couple students per class that can't become a field officer because they are color blind or have some other condition and so they spent 4 years of college then found out they couldn't do what they wanted. you could do it and spread the word to other programs to have their freshman students get eye exams early.
probably not enough there to do a full senior project on though eh?
