These arseholes will move on to a different breed and a few short years same problem different dog. Ban dogs they will get a boa constrictor if they think it makes them look tough! These people do not care about laws.
I agree with licensing, registration, training, insurance, and vet registration, but these types of people don't.
I would put good money on the revolving door of courts is part of their lives. We need an effective judicial system. Removal of all dogs pets from homes as part of punishment. Effective prison sentences, prison works, its not being in them and releasing when they are, that causes problems, SS involvement if there are children in homes of criminals as routine.
Funding and resources to do it are needed, but until it affects Joe Bloggs MP, and his kid is killed, nothing will happen, and MN will continue to froth.
I say this as a dog owner who every weekend is out at dog club activities/ training. I have a strong, large dog. ( not bully breed) . I spend time and money on my dog training. Even though she is now an adult, we still do classes every week and will continue to do so.
