They will not alarm the WTMD. However, keep in mind that if you go through the WTMD wearing a vest, you're going to be screened in secondary. We specifically look for bulky vests worn underneath clothing. (Just to clarify my previous post, there is nothing prohibited about having a bullet proof vest in your carry-on; however, wearing one certainly draws a lot more attention and scrutiny. I would hope this to be obvious.)
