They did, that's why I said "team" in my response, however I will elaborate for you.

two Devs must review and one dev lead has admin rights to push to protected branches. Problem is when the whole team is not meeting expectations and they all jerk off eachothers bad code.

My team reviews internally just like they did, the issue isn't the review process. At a professional level you should trust your peers therefore the issue was the hiring and/or training process
