Can't find a link to this story but basically they are discussing law changes which would mean that a man can't use the 'excuse' that his wife was a nag or had an affair as provocation.
Seems to make sense to me, but seems like people are arguing that women are allowed to cite provocatioon after abuse (physical or mental) and so it's not fair!
Big difference between killing someone because they are a nag and killing someone because they are abusing you! Don't you think!?
