Why don't officers wear marksmanship badges?

YES!

They don't want to show the enlisted that they are bad at Marksmanship.

This is obviously an Army cultural issue or tradition. I can say with rare exception ALL Marines wear rifle and pistol badges when appropriate.

No disrespect to those who responded otherwise and i dont disagree with comments about our roles synchronizing and leading the group. But, i was an OCS commission and many of us wore our marksmanship badges. I was expert rifle and pistol, and happy to wear it. As a paratrooper, we were all expected to be infantry until the objective was seized and then whatever role you transition to later. Infantry first.... and thank God i could shoot or i’d be dead today. One of the greatest men i ever worked for, LTG Robert Flowers used to say ... “Be in great physical shape, be an expert with your weapon and know your job. If you do that your men will follow you and you will succeed.” My soldiers were proud to see that the old man could hold his own on the battlefield and i had earned the right to wear it so I did. Airborne all the Way!

If no other officers wear them then no.

I like the discussion here. In my experience, I've either had officers who can't shoot and aren't necessarily required to due to the fact that they are leading troops and directing PLT SGTs and SQD LDRs to place fire at whatever location needed at the time OR I've had officers who shoot better than anyone in the company/battery/troop and they are told by their CO or BC to "not be a cowboy." There's also the reality that your marksmanship badge will help you out in promotions and boards on the enlisted side (in most cases), but it's sort of a moot point on the officer side as officers are often expected to be the best. So it seems unnecessary for an officer to put on a marksmanship badge in some circles. That shouldn't take away from the fact that every trooper, regardless of rank, gender, or branch of service, should be proficient with their assigned weapon because if you cross the LD, there WILL come a time in which you need to use it.

Marine officers do. Part of the uniform, and besides, you EARNED it (not like a lot of the things I see on others uniforms).

I thought it was a matter of practice and not regulation. A practice related to officer leadership and the fact that an officer is expected, by virtue of rank, to be an expert on such matters. However, it isn't a uniform practice, as I have seen Army officers wearing their badges. In my case, in the Air Force, marksmanship proficiency is demonstrated by a ribbon and not a badge -- a ribbon that is sought after regardless of officer or enlisted. As you can see, I'm proudly wearing mine and still remember the cold, wet, windy day I earned it.

As was explained to me it’s more of a tradition than a regulation. I have never seen anything in AR 670-1 profiting officers from wearing the badges.

Most officers would respond with a reason, to lead is to inspire, and if my qualification is not up to snuff, therefore how can I lead. Officer or Enlisted regardless of rank, some people shoot excellent, and other's, well lets just be truthful, they suck!! Shooting is a learned skill, and is perishable one at that; if you as an officer want to lead by an example and inspire your troops, then hit the range more than once a year; organize shooting competitions at the unit level to inspire your soldiers to learn to shoot better, not just a rifle, but with a handgun/pistol what ever is in your units armory. We are all Infantry; we need these skills, and what a better way to improve your skills getting that expert shooting badge while wearing it with pride on your chest to inspire and lead by example, because you truly earned it. Not only that "Sir," I promise your shit isn't in the wind for two reasons; one, you spent some time having fun training with your troops, working with and learning marksmanship. Two, when the time comes on the battlefield, you and your soldiers are wasting less ammo due to familiarity of weapons and greater confidence of shooting skills, which means less wounded on your side of the ditch and more on theirs.
