AC,

Yes. All a bit of media hype on a quiet day, probably. It would be pretty silly for anyone Howard's age (and mine) to interfere in domestic violence when both parties often turn on police unlucky enough to be sent to a domestic.

Is Mise Add to that what I stated before "statistics from the US that more people had been saved by someone with a gun intervening than had been killed by people with guns"

Also If a criminal wants a gun they will get one, it does not matter to him or her how.

I'm not certain but I have heard of countries which have Military national Service where those who finished the two year service then keep a rifle in the home.
I believe the Swiss have the kind of mentality that allows that policy.
