“Enjoy the rest of your day, and rest assured this will all happen again very soon.”

With chilling indifference, Bowling for Columbine director Michael Moore perfectly summed up this weekend’s mass shooting at the University of California Santa Barbara in a post on his Facebook page.

“With due respect to those who are asking me to comment on last night’s tragic mass shooting at UCSB in Isla Vista, CA,” Moore wrote, “I no longer have anything to say about what is now part of normal American life. Everything I have to say about this, I said it 12 years ago.”

Moore, whose controversial 2002 documentary explored the causes of the 1999 Columbine High School massacre, placed the blame on all American citizens.

“Even when 90% of the American public calls for stronger gun laws, Congress refuses,” Moore argued, “and then we the people refuse to remove them from office. So the onus is on us, all of us.”

The director specifically highlighted the fact that most mass shootings in the US are committed by “disturbed white males” who are still legally able to access firearms.

Comparing the US to other countries like Germany or Canada, Moore pointed out that while many share similar cultural circumstances, their lack of guns significantly reduces their rate of murder.

“While other countries have more violent pasts (Germany, Japan), more guns per capita in their homes (Canada [mostly hunting guns]), and the kids in most other countries watch the same violent movies and play the same violent video games that our kids play, no one even comes close to killing as many of its own citizens on a daily basis as we do.”

Moore closed his online spiel with a powerful statement:

“When the NRA says, ‘Guns don’t kill people – people kill people,’ they’ve got it half-right. Except I would amend it to this: ‘Guns don’t kill people – Americans kill people.'”
