It was easy for them to get firearms.
And if guns were banned tomorrow, they'd still find it easy for generations to come due to so many in circulation. Not to mention, we have a problem with the whole gun banning thing and prefer to retain our arms. It balances out to the good, at least according to the sum total of most studies.
As it did in this case.... two armed robbers shot, no good guys hurt, that's a win IMO.
CDC Study: Use of Firearms For Self-Defense is ?Important Crime Deterrent?
Cars are not designed and marketed to kill people, guns are.
Utterly irrelevant. Dead is dead, and cars kill 40x more children than guns.
Americans have granted themselves the freedom to cause many deaths to our world through foreign wars and entanglements.
Beyond the scope of this discussion really, but I suppose I invoked it a bit. Let me ask you a question.... WHY and HOW?
HOW: We can, because there are none who can equal our ability to project force.
WHY: More complex, but in part because if we didn't dominate world affairs, someone else would, and they (Russia, China, other regional powers) would order it according to what was best for THEM and THEIR interests, not ours. At least you (UK) get the benefit of being a close ally and having the ear of the current world superpower. If you don't like it wait around... it changes every 50 or 100 years, perhaps the dominance of Russia or China or the future Caliphate will be more to your liking than the Pax Americana.... though I doubt it.
In any case it is another example of how force rules the world. Those who beat their swords into plowshares soon end up plowing for those who do not.
Who does American not push around? Well, those who have nukes, and might be able to send us one. On a more personal level, it works much the same between armed individuals and disarmed ones.
