The guards at Naomi's wedding are shown being armed, implying that they're legally allowed to shoot any low-score who tries to enter their premisenote why they don't shoot Lacie at the wedding can be chalked up to how bad it would look to kill someone within sight of the wedding guests rather than at the perimeter. In this society, The Beautiful Elite are allowed to shoot you so they don't have to breathe the same air as you. Given how interacting with the poor can lower their score, it's actually a valid concern for them to use lethal force to keep you as far away from them as possible too.
