"It IS different."
It's fair to say that finally some forces are dealing with the crime if DV, as they should do.
But some still aren't.
In fairness, DV isn't the only situation that isn't always got right.
But we have to tackle each issue, to find out why this is happening.
Anti Social Behaviour, dangerous dogs, drugs, being ignored (for instance), will all have different reasons to DV not being dealt with as it should.
But then there isn't one answer, different cases, have mistakes made for different reasons.
A recent DV murder in my area was because of a lack of recognition that the victim (under 18) shouldn't have been allowed to take control and was incapable of doing so (for many reasons) so protocol should of clicked in.
There wasn't enough done to protect her child either.
Taking women out of the equation and fully letting Child Protection step in, stops the reporting.
Although changes need to be made in some forces, they are not going to be popular, even with the victims.
Then the CPS back away from some crimes of violence (but not benefit fraud).
