Exactly what is the jacket removal policy? I have seen men in suit and sport jackets allowed to wear them and walk through the metal detectors in most airports. Some airports make you take them off. Anyone with an overcoat has to take it off and be scanned with the bags, shoes and other miscellaneous items such as cell phones and laptops. However if you are wearing a leather or suede sport jacket (not an overcoat) they ask you to remove them.
