Fraud or Anti-Money Laundering Investigation Careers

Looking to make a career change and this seems interesting.

I'm a former police officer from two large municipal departments. Some FBI certs, history of training/instruction, background in safety, background in investigations and some intelligence analysis.

Seems like the pay is decent, but nothing to get excited about. This would be an entirely civilian gig with the likes of major banks (Cap One, Chase) or insurance groups (USAA, etc.).

Anyone here have any insight? Certs to acquire prior to application? Pros/cons?

Thanks in advance.
