For all my CJ majors

I just finished my bachelors in both psychology and criminal justice and am looking into grad school.

I originally wanted to for my MS in forensic psychology. As I continued my research, I found a school that offers me the opportunity to get a dual masters in forensic psychology and legal studies. Its 52k for two years.

Is it worth it getting an MS in legal studies too? My cousin who’s a cop said no and to go with just forensic psychology and go for a school that’s like 21k a year.

Need advice.
