I don't think it matters. If you accidentally brandish, you've shown the butt of your firearm either way. How high the holster rides is of no importance in this case.
As far as offending LEO, their job is to enforce the law. Some will be offended by the simple act of you carrying a fire arm. Others will encourage it. Your holster choice shouldn't be any of their concern much less worry if they are offended by your carry rig.
Worry less about offending and more about carrying in a safe, legal way that is comfortable and most importantly, comforting for you.
