Why? Like everyone, I'll have my pet theories. With respect to violence against women, I really think it's a combination of us (society of women of Ireland) not being well informed enough, being too passive and accepting things as we struggle with other priorities. Frankly, it's also easier to ignore these things.
I thought at different times like after the Kerwick case, the Cratloe case, the Roche-Kelly case, that things might change, but ... no ... There will be a lot out outrage as a result of the current case in Croke Park, but that will dissipate quickly too.
Regardless, I think the system is better now, than in the more recent decades. However, that's totally due to very brave selfless individuals, and a small amount of campaigners/organizations.
Those of you old enough to remember the Lavinia Kerwick will know that was pivotal. Only her personal bravery, and a supportive radio personality. brought that to national attention. The same with the RCC and their activism.
Finally sentencing is just one aspect, and it is too late. There needs to be a lot more done on prevention, reporting, policing and scheme's like Clare's Law.
