The truly frightening thing about the shooting that killed five military members on Amnicola Highway last week: It could happen again, and it's hard to stop.

"If it can happen in Chattanooga, it can happen anywhere, anytime, anyplace," U.S. Rep. Michael McCaul, chairman of the U.S. House Committee on Homeland Security, said Sunday.

McCaul, a Texas Republican, said on ABC's "This Week" that the FBI is doing forensic examinations of shooter Mohammad Youssef Abdulazeez's cellphone, computer and trips to Jordan to determine if he was involved with ISIS, also known as ISIL or the Islamic State.
