This morning on America's Newsroom Martha MacCallum spoke with retired Staff Sergeant Alonzo Lunsford, who survived the 2009 Fort Hood shooting.

He reacted to Wednesday's shooting at Fort Hood in which three people were killed. The suspected gunman was an Iraq war veteran who reportedly suffered from mental health problems

Lunsford suffers from post-traumatic stress disorder, and said that not enough has been done to help mentally ill servicemembers.

One of the ways Lunsford deals with PTSD is through K9s For Warriors. He said having a service dog helps give balance for service members and their families.

Lunsford thinks we aren't doing enough to help soldiers with PTSD, "A lot of times these service members are asking for help. Give them that help without putting them on a wait list. Give them that help without giving them medication that's going to have them walking around like zombies."
