WASHINGTON, May 4 (Sputnik) — Extremists cannot justify violence by claiming that acts of expression, such as the Garland, Texas cartoon contest on the Islamic prophet Muhammad, are offensive, White House Press Secretary Josh Earnest told reporters on Monday.
"In the mind of the President [Barack Obama], there is no form of expression that would justify an act of violence."
"We saw a pretty important and notable display of bravery on the part of first responders and… because of their courage, the only person that was injured by these gunmen was a security officer," Earnest added.
The US Federal Bureau of Investigation has identified one of the shooters in the attack as Elton Simpson from the US state of Arizona. The authorities had investigated Simpson in 2010 for his alleged connections with terrorists, according to local media.
