Ms Ambler told the BBC: "If Rob hadn't had access to such a deadly weapon, there's a chance that Kelly, Ava and Lexi could still be here.
"This could have been prevented if gun licensing guidance was tougher."It's not already tough enough? And deranged men and women haven't managed the same result with ordinary household items?
Kelly’s family want to see people who lie on their applications banned from re-applying, as well as licences to be reviewed more frequently.
Which wouldn't have done a single thing to prevent this murder, because it only came to light after he'd done it. And where are the police going to find the time?
They also want closer working between GPs and police forces and for people with recurring periods of depression to be barred from getting a licence.
That'll be good, since the GPs are just sitting there twiddling their thumbs, waiting for something to do...
