Dishonesty in the work place

So I work at a Credit Union in the Collections department. Once upon a time I was the only manager of the department. Then I decided to try a different aspect of life and joined the LA County Sheriffs department. Had some a series of things happen and experiences and learning that I decided to hold off on that part of my life. So, I decided to go back to school and shoot for the FBI. I came back to work at the Credit Union in the Collections Department. They had replaced me with another guy and then put me back in as well do be my own supervisor and really kinda my own department handling different aspects of Collections.
When I was the Collections Manager I was always honest and straight forward in everything I did. If I told someone what they needed to do in order to clear their late account then that is what they needed to do and stuck to that and never changed it. When someone came to me and made an arrangement with me, i never changed the arrangement without first talking to them. I never lied. I never stole. I never cheated anyone. I like to think I ran my office very honestly and my employees ran things honestly.
The new manager that works in the office I have come to learn does not have the same work ethics that I have. For example he spoke with a lady who said she was trying to sell her car and get us paid off. She said she was in a hard circumstance and was going to work through it with us. To me it sounded great and the new manager was the one of the phone with her. He told her that he had no desire to repo her car and wanted to work with her. He obtained her address and phone numbers, then once the phone call was over he sent a repo agent to pick up the car. The people called back very furious that he had repo'd the car even when he promised he would not. Then when he got in trouble for this instance from our President of the Credit Union he turned the blame on one of the employees, that employee had nothing to do with it but yet he was blamed for it by his superior. Other times we had people calling in saying that this certain manager threatened them or made claims that were false or just straight up lied to them.
One day this manager sat with me and another employee (who is a personal friend) and told us that we were getting to comfortable and we were not working. I didn't say anything but looked at him with what must have been a very disgusted look because he quickly changed the subject.
Then today I'm working and researching some accounts that we had charged off only to find that he has been taking sale proceeds from accounts before they were charged off and reapplying them to the loans after they were charged off so that they will look like its recovery. So in short without getting into anything confusing...he is taking money that's already there, deleting it, and putting it back on there so it makes him look better. By doing this it looks like the amount charged off is much less than the amount we have obtained in recovery in turn making him look like he is doing good BUT if you look at it from what i've found...he is actually not changing anything other than padding the numbers a little bit.
Also, as I have done my research today I have found accounts that are just not being collected on and no repo orders are being issued. The collection policy is being taken spastic at best and no two people are getting the same treatment from him. I believe if you are going to do something for one person then every person is entitled to be treated in the same manner.
Now I have the dilemma on what I should do. I have come across things that to me seem dishonest and not a way to run a office. In my feelings I feel bad about it and it stresses me out. I don't really know who to talk to about it because I don't know how is turning a blind eye to such a thing. My current plan is to talk to my boss, President of the Credit Union, and explain to him what is happening and leave it up to him to do something.
Oh yeah did I mention that we have been sued more times with him in the few months he has been here than ever in the 50 years the Credit Union has been open? Oh yeah that's another wonderfully true statement.
Unforturnatly not the entire world likes to see things as working honest in their dealings with their fellow men. I will not be one that turns a blind eye to dishonesty or cheating. Turning a blind eye would mean that I'm okay with that type of behavior and I am not okay with it.
