Many incorrect facts here. They are hyping it for all it’s worth. If he had used ball ammo or penetrator ammo, the story would be that he was using “cop killer” or “armor piercing” ammo.
I expected, and am seeing, the US and international MSM to hype any and all anti-gun angles in spite of this being another great case for 2nd amendment. A few random armed civilians there certainly would have lessened the losses. Heck, even if just the off-duty cop doing private 'security' work (the princess's step-brother) had been armed 68 lives might have been spared. I hope some of the victim's parents can see past their own grief and their own political biases to see the real picture. They now control the government and if they choose to act because of this event they can do as they want. They have the power to improve things, or alas to make them worse.
