The Atlantic Wire 
Shootings at Fort Hood military base  in Texas have reportedly left 12 killed and 31 wounded. Details on the events are still emerging and there is much left to know about what happened and why. As coverage unfolds, journalists and pundits are using Twitter to debate and theorize on the violence. Much of the discussion centers on media coverage, which many criticize as overly speculative, and on the shooter, Army Major Malik Nadal Hassan. (Please note that information on the event is incomplete and as the story develops these tweets may reflect old information.)
On Speculation of Terrorism:
National Review’s Kathryn Lopez : “re fort hood: why do we reflexively rule out terrorism?”
Activist Jim Gilliam : “‘is this an act of terrorism?’ is code for ‘did a muslim extremist do this?’ obviously, it’s an act of terrorism.”
ABC’s Jake Tapper : “This is a time for the best in Americans to come out, not the worst. Let’s donate blood, pray, have well wishes, stick to facts. No word on motive yet and at a time like this ppl should listen to their better angels.”
The Atlantic’s Marc  Ambinder : “Sad that US Muslim groups feel obligated to rush out statements condemning the murderous actions of one American Muslim. Sadder still that folks are presuming to know what motivated the killer/killers…and blaming it so quickly on Islamic terror/jihad.“
On Malik Nadal Hassan:
Salon’s Mike Madden : “How long before some idiotic elected official declares Muslims shouldn’t be allowed to serve in the military?”
The American Prospect’s Adam Serwer : “Please America, remember what kind of country you are right now.”
The Nation’s Jeremy Scahill : “Right wing blogs in full swing, calling allgd ft hood shooter a jihadist and “not likely Amish” bc of alleged Arab name.”
Media Matters’s Oliver Willis : “ppl jumping to conclusions either way because of this guy’s name are likely… jumping to conclusions“

Media Matters’s Oliver Willis : “oddly fox seems to be showing the most restraint with this story. the shep [Smith] effect?”
Jarvis J : “Oh Lord, Chris Matthews is only good at jumping to conclusions. Take him off the air for now. Jesus. By the time Chris Matthews finishes speculating, Osama bin Laden himself will be at Ft Hood.”
Daily Kos’s David Waldman : “24/7 cable news has no choice BUT to speculate. What else can they do for the 23 hours and 58 min left after they tell you what’s known?”
Conservative blogger Allahpundit : “You know when it’ll be perfectly PC to speculate about Hasan? When cops find one of Glenn Beck’s books on his bookshelf“

Thursday, November 5, 2009
At least 12 people were killed and 31 others were wounded in a mass shooting incident Thursday at Fort Hood, Texas, military officials said. The shooter was shot to death, they said.
More shots were reported later in the afternoon, reported NBC affiliate KCEN-TV of Waco, which said no further details were immediately available.
A senior administration official told NBC News analyst Roger Cressey that the suspect who was in custody was an Army major with an Arabic-sounding name. The official said the shootings could have been a criminal matter rather than a terrorism-related attack and that there was no intelligence to suggest a plot against Fort Hood.
It was unknown whether the victims were all soldiers or civilians at Fort Hood, one of the largest military complexes in the world. The base was on lockdown, as were schools in the area.

KCEN, which quoted a source as saying at least one of the shooters had a high-powered rifle, reported reported that at least four SWAT officers were among those wounded.
A spokesman for Fort Hood said the shootings took place at two locations around 1:30 p.m.: the Soldiers Readiness Processing Center and Howze Theater.
The spokesman, Sgt. Major Jamie Posten, said processing center was where soldiers “cycle through as they prepare to deploy.” That complex is on the West side of post, off Battalion Avenue.
Greg Schannep, an aide to Rep. John Carter, R-Texas, who was on the post to attend a graduation service, told the Austin American-Statesman that a soldier with blood on his uniform ran past him and said a man was shooting.
