Students and victims' family members attended a memorial Tuesday evening for those killed in the rampage at University of California Santa Barbara. Six UCSB students were killed on Friday. About 15,000 people assembled to remember the slain and condemn firearms.

A 22 year old student fatally stabbed three men, shot a man and two women, and then ran over some innocents.

No mention was made of banning knives or cars. Just guns.

One thing would have stopped him. A gun.

There weren't any. He was in a gun-free zone. A college in California.

A gun did stop him. His gun. He shot himself.
