U.S.: 5-year-old and 8-year-old Shoot and Kill Younger Siblings This Week [updates]

The NRA is having a big conference today. They're really whooping it up.

In related news: "5yo boy accidentally shoots and kills 2yo sister":

A two-year-old girl has become the second child in the US to be shot dead by a sibling this week, after her five-year-old brother shot her with a rifle designed for children, officials revealed on Wednesday. Officials in Kentucky say the five-year-old boy was playing with a rifle designed for children and given to him as a gift, when he accidentally shot his younger sister.

Here's the story of the other child mentioned.

Update: Also this week - 3-year-old shoots and kills himself with grandmother's gun.

Update II: From Greg Mitchell: Dashcam footage from March of a guy firing a semi-automatic rifle at cops, shouting "Kill me!" (They killed him.)

Remember this when you watch this guy firing that semi-auto right toward the camera: You're seeing something approximate to what the kids at Sandy Hook Elementary saw.  This is what a semi-automatic rifle can do.
