Agree. Sure, when the ban is in place there will still be scumbags who have these dogs. The ban should mean that the earlier instances of anti-social behaviour that have been reported prior to some of the deaths will give a mechanism to stop things escalating to actual deaths and life-changing injuries. (Hopefully this will also help the very many people who have had dogs attacked or killed.)
However, if it stops standard families having such dogs because it is expensive, restrictive and no longer 'socially acceptable', then it will also stop some of the other stuff. So many stories of these dogs being 'loving family companions' ... until they weren't and caused horrific damage or death.
It still utterly bemuses me that people deny there is an issue and lump these dogs in with GSDs, Dobermanns, etc. The sheer numbers and years of integration within society of 'standard' breeds in comparison to the relative recency and fewer numbers of XL Bullies, yet so many more serious attacks is just undeniable.
Even when there are deaths caused by other breeds, they are usually (not always) incomparable - looking at the list of deaths by 'other breeds' they include tiny babies, small children, infirm adults (including epileptic seizures), drugged dogs(!), adults who have died from complications such as sepsis, rather than directly being killed by the dogs.
'Staffordshire Bull Terriers' do feature, but anyone who knows what an SBT should look like will know that SBT is a very wide remit that mostly doesn't remotely resemble the actual breed.
