I agree that there can be no reason for anyone here to own a gun.
In the past, farmers would shoot crows, pigeons and other crop-munching birds with a rifle. Nowadays they use 'bangers' (a loudspeaker thing which can be set to go BANG at a frequency one chooses) which are effective at moving a flock of birds off the fields.
I personally despise these consortiums of wealthy businessmen/enthusiasts that go grouse shooting (the season started on August 12th - the 'Glorious Twelfth') slaughtering 'game birds' by the hundred. Horrible, but I daresay they adore the activity - it's seen as a 'sport'!.
However, if one is feeling murderous, one can knife people to death (knife crime is increasing frighteningly among young people in the big cities)
I'm mainly interested in the psychology behind all this. And at what point does one decide a perpetrator is mentally ill or just wicked and deserving of a life-sentence?
Dunblane was apparently the result of Thomas Hamilton's feeling of exclusion and rejection (!!)
I suppose I could boil all this down to a simple "What makes people kill?"
