Well, its all going about as expected by those against the ban on the grounds that it would not work (not that something shouldn't be done, just that the ban would be any sort of a solution) to reduce/stop attacks/deaths.
If that photo is of the dog (it does suggest it is) then I can immediately see that the owners have been ill advised on muzzling, that muzzle is not appropriate for exercise, it works by physically strapping the dogs mouth closed, which stops them breathing properly or panting to cool down. Such muzzles are only appropriate for a few minutes during grooming or veterinary procedures, and this is not some obscure detail, this is widely known and publicised when discussing and buying muzzles.
If they can't get that right... what else have they got wrong out of ignorance?
The ban has not addressed the poor housing, handling, training, lack of socialisation and management that heavily contributes to attacks.
As such we will still see attacks, though more in peoples homes than out, as dogs are kept at home more, walked and socialised less (particularly if they are a problem on the lead), and so become more frustrated as their needs are not met. (More frustrated = more unpleasant/hard to live with behaviour = more heavy handed punishment and neglect like caging/crating for hours, not getting the exercise they need. Its a vicious cycle that leads to fearful, explosive, unhappy dogs and at the size XL Bullies are... that is dangerous.)
I'd like to see stricter, harsher punishments for owners. Historically, particularly when a dog kills or injures the owners children/relatives child, this hasn't been done as the view tends to be that the parents have already suffered enough - but that isn't how we deal with other causes of death where the parent is negligent and puts their child at risk!
We really need to stop pushing the responsibility and blame, onto the dog, and put it squarely on the humans who bought, trained, handled and housed that dog, and chose to put a child into the mix.
