Hollywood, the Beltway and gun reform activists – including the Parkland, Florida students who have taken an impressive lead on the topic – responded quickly to today’s shooting at Santa Fe High School in Texas. The shooting left 10 dead, including nine students and a teacher. A 17-year-old suspect is in custody, along with a second person, possibly an accomplice.

“Prepare to watch the NRA boast about getting higher donations,” tweeted Parkland survivor Cameron Kasky. “Prepare to see students rise up and be called ‘civil terrorists’ and crisis actors. Prepare for the right-wing media to attack the survivors.”

Kasky’s schoolmate and fellow activist David Hogg wrote, “Get ready for two weeks of media coverage of politicians acting like they give a shit when in reality they just want to boost their approval ratings before midterms.”

“We can do better than this,” tweeted Ellen DeGeneres. “We must do better than this.”

Among the politicians weighing in were President Donald Trump, Canadian Prime Minister Justin Trudeau and L.A. Mayor Eric Garcetti.
