Re: 5 year old given rifle as gift, kills 2 year old sister
^ Note: We all don't live in the parts of the country where the police are three minutes away. People who live in the boonies realize that it will be half an hour, at best, before anyone arrives, and then another half hour before they figure out what approach to take.
ETA: And also, a pump action shotgun would've done just as much damage, if not more. Heck, based on old US Army tests, killing 26 people with an 1819 Hall flintlock would've taken only 8 minutes 14 seconds, assuming that the assailant didn't just start bashing in skulls with the butt of his rifle.
And people living in rural parts of countries like the UK, Australia etc.. might live in parts of their country where the police might be 30 mins away as well.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
