I'm so sorry. Truly... and I understand the need for justice and the anger you are feeling. And right now, I'm sure you do not care about the consequences that confronting him will bring. But one day you will...
2 1/2 years after my d day, I am so glad that my brother stopped me from going to confront my husband's lover. I was filled with rage and didn't care. But now, I am thankful I didn't. They aren't worth it.

I can remember one day when I discovered my H and his slut were still seeing one another. I surprised him at work and I was ready to throw the slut out the window of a high-rise office building.
I had texted my therapist who said one thing: Do not lose your dignity.

Those words calmed me down and the slut still lives.

I do think it is different for men though. I think it's fine if you confront this guy. But I'd keep it simple. With witnesses I would tell him to keep away from your wife. There is nothing wrong with that. Just do not lose it. Keep it calm. Walk out after you tell him to stay away from your wife.
No threats.

They are both in law enforcement and you're going to go over there and do what? You'd be better off telling their captains or supervisors about the situation. Writing what you have is not cool, not even as a joke. You need to do some growing up, and right about now would be a good time. You can't force her to do anything she doesn't want and if that is her choice, to cheat with him, then let her go and move on with your life. Don't do something stupid that will backfire and put you in jail. Go and see a pastor, or counsellor, but using violence and or anger to deal with infidelity and affair partners is the wrong way to go.

I appreciate all the advice, I did go there as soon as he seen me he turned like a ghost, my first instinct was to beat his ass, but I have 2 boys who need me, right in front of all his coworkers I told him this weekend would have been my anniversary to my wife but since you and her are both low life's I filed for divorce thanks to him. I also told him he destroyed a family and there is 2 people who got hurt the must, my kids. As I was leaving one of the captains called me over and spoke to me. He explained he went through this where his wife cheated on him and was surprised how I handled it and congratulated me. He also said he would make sure he assigns him some really shit details. Since my wife and him work at diffrent commands I don't think they know who I am married to.

Brother, looks like we got dealt the same hand. I'm going through a recent divorce. Back in January, my wife asked for a trail separation. She said it was due to my anger and temper. I begged and pleaded with her not to do it. I told her I would get help and better myself., and I did.
4 months into our separation, she acknowledge the change in me, the relationship with our 3 kids was getting better, she gave me hope.

And then, BAM!!! just like that, towards the end of April, I found another man's shirt in her dresser..i confronted her about it and she came cleaned.

During our 4 month separation, me getting help, still upholding my responsibility as a husband and father, helping out with our kids. Watching them until she got home late from work. Through all of that, she had an affair, which turned into a relationship. She gave me false hope. She destroyed me and my future with my kids. Cause naturally with her, I was the cause of our marriage ending. WOW!!

Sounds like you handled it correctly.
I applaud your reserve. No cheater is worth landing yourself an assault charge.
My bet the dude will dump your cheating wife's ass and she'll beg for forgiveness.
Watch out.

as nuch as the guy is a shitbag, your soon to ex wife IS the much bigger shitbag, her choice to piss on her kids nest
her choice
