Although the two things may not be related.
Clearly badly bred bull-breeds and dogs being bred by criminals are a huge issue atm and police and other agencies need resources to investigate and prosecute breaches of the law currently. I haven't had a chance to watch the BBC programe but it sounds like that might help drug law enforcement too.
The dog bite trend has been rising for longer than bull-breed ownership. And the vast vast majority of bites are in the home by the breeds most of us own - so there will be plenty of little chihuahuas, cockerpoos etc making up the dog bite stat. My understanding is it is rising faster than the rise in dog ownersip, so more dogs are in homes where they end up biting. That's really worrying too but prob needs different enforcement - safeguarding interventions if a child or anyone vulnerable is bitten, mandatory training for dog owners after a bite occurs, muzzle orders etc. Again the current law allows for all this, and prob in many cases dog control orders are used. I don't know how easy they are to enforce for police and in some cases working with dog owners to make them better informed may be better than force (if people fear removal or muzzle orders they may just not seek appropriate medical attn which would be the worst outcome).
