Two things struck me about the incident (I read the Guardian article on this incident):
A member of the public died, in public. Not the dog owner and not in the owners home. This is significant. Another member of the public is in hospital.
Seven dogs were rounded up by police. Seven. This wasn’t one rogue dog.
Bear in mind that the articles we see in the press are the tip of the iceberg. Over 8000 hospital admissions annually. And that’s just the people who go to hospital - lots more than that are actually bitten.
There is an odd indulgence for dogs in the UK - let your kids outside to scream at 6am and you’re a pariah but complain about dogs barking outside at 6am and you’re an evil animal hater.
Even the Queen indulged her snappy Corgis….
As others have said, too little regulation and next to no enforcement.
No requirement to train dogs (in some European countries dog training classes are mandatory and enforced but not the UK).
Little accountability within the police force - they’re supposed to have specialist dog units but many don’t and will look blank if you ask.
Of course people are going to be injured or worse. But who dares lobby for reform when so few voters will support it.
