It has been 29 days since the last double digit mass shooting in the US.
During those 29 days, there have been 60 mass shootings with 48 killed and 259 wounded.
The Highland Park shooter is a young white male with a rifle. This will be the top news story for the next several days while the rest is largely ignored. The lie that white males commit the majority of mass shootings will proceed as normal.
Even that 'top news shooting story' will proceed as normal, don't worry. Regardless if the murderer is black, white, asian, latino, or venusian, the scenario is already written.
First, there will be 'mourns and prayers'. We'll see people putting flowers, candles and pictures. I guess the New York Times will make another of their impressively moving photo article, and interview the families. There will be the president's speech, too, where he'll tell us all how unacceptable it is in America.
Next, we'll see people on the Left side of the debate shouting "it is GOP's fault !" They will of course conclude that Republicans somehow usurped power and will shout "Vote to change things!" everywhere, and ask for stricter laws. Those on the Right side of the debate will come and defend "the American Way", denounce the attacks against individual freedoms and call for more self-defense rights.
Both sides will fight on page 2 and 3 of the newspapers, then on page 10 and 11. And on twitter, of course, trading crudely edited pictures with political messages in big red or blue letters, each ending with "Shame on you!!!".
The most reasonable people will argue on how 'check and balances' are still checking and balancing things, and conclude to not conclude.
And, in the end, nothing will change. Not a single bit.
So don't worry if only some of those murders get the headlines; it is mere sensationalism. The overall effect is the same - people die, and nothing changes.
