Muslim organizations have condemned the shooting attack at Fort Hood last week by Maj. Nidal Malik Hassan, and some Muslims have worried that it could fuel negatives perceptions of Islam.
Add the Army chief of staff to those who are concerned.
"We have to be careful," Gen. George Casey said Sunday on CNN. "Because we can't jump to conclusions now based on little snippets of information that come out. And frankly, I am worried – not worried, but I'm concerned that this increased speculation could cause a backlash against some of our Muslim soldiers. And I've asked our Army leaders to be on the lookout for that. It would be a shame, as great a tragedy as this was, it would be a shame if our diversity became a casualty as well."
Sen. Lindsey Graham, a member of the Senate armed services committee, also counseled restraint.
"At the end of the day, maybe this is just about him," the South Carolina Republican, a colonel in the Air Force Reserve, said Sunday on CBS. "It's certainly not about his religion, Islam. It's not about the Army; it's not about the war. At the end of the day, I think it's going to be about him."
