Axl's answer =
The # was random but the sequence is intentional.
It's a line from the book used to infer it may have helped to inspire a senseless killing.
I belive that's 1-0 to me guys 
And I shall clarify, as I have actually read the book, "Catcher in the Rye." I even had a thread about in the Whatever section.
A body took a body is sung by a little boy in the book. Holden Caulfield hears it and it sticks with him. Later, he talks to his younger sister and she tells him it's actually from a poem about children playing in field of rye, which is a grain, most times used in bread. So, Holden builds this fantasy of himself as being in the field of rye, which is next to the edge of a cliff and he is there to prevent the children from falling off the cliff by catching them as the wander toward that edge. Hence, catcher (as in kid catcher) in the rye. Many have taken this as Holden seeing himself as a protector of innocence, where falling off the cliff is the lost of innocence, something he, himself may be avoiding. He comes closest to being the self-appointed catcher in the rye by not leaving his family after all. His sister was going to leave and he couldn't allow her innocence to be crushed in the cold, hard world. So, he sacrificed his run for freedom, stayed, and wound up in a hospital and writes the memoirs that are the bulk of the story.
The line "who gave the boy a gun" is not in the book, or the poem inspiring the book. That is a line from Axl, wondering, as I have, how Mark David Chapman could interpret the book "Catcher in the Rye" as an inspiration to kill John Lennon. It is also a damnation to the person who provided Chapman his gun, even if there was no direct link.
The character, Holden Caulfield singular fails at most any act requiring concentration and focus, except for writing. But the story starts nowhere and ends nowhere, with a lot of nowheres in between, with no detectable maturation or growth in Holden, save for what I see as is one moment to step out of his self-absorbed world to protect his sister, and maybe a hope that he may one day find purpose.
