Welcome to the Shining Beacon on a Hill, the example to the rest of the world, where we've had 294 mass shootings in 274 days so far this year:
We've gone no more than eight days without one of these incidents this year. On six days in September, there were 3 mass shootings or more. If the initial casualty figures in Oregon hold up, that would bring the total of deaths by mass shooting this year to 380 so far, with well over one thousand injured.
And of course, there's the broader universe of nearly 10,000 people killed and 20,000 wounded in nearly 40,000 gun violence incidents so far this year.
This is the United States, where a group dedicated to selling guns has successfully captured firearms regulations, subverted a Constitutional protection for states (not individuals) against central government over-reach, and shut down rational argument on the merits of having this much firepower available to this many people for this long.
