Disgruntled nut
With an automatic weapon
Stalking the hall
Bursts into the classroom
Couldn't be more dire
Finger on the trigger, starts to open fire

I'm throwing rocks
Aim for the gunman

They've built walls
And fortified the doorways
Cameras for surveillance
Wear see-through plastic backpacks
Raise gun purchase age
Ignore the threats he posts on Facebook page

Start throwing rocks
That's gonna stop him?

First blame the gun
Then the ones who didn't do it
While the warnings went unheeded
Now the cops have all departed
The lawyers have arrived
And we'll pay to keep this murderer alive

We have the rocks
Where should we throw them?

You're on your own
There's no deputy to protect you
He is waiting for the SWAT team
When at last they come
Evil deed's been done
"Secure the scene and tally up the dead".

Just throw some rocks
Hope for survival

Yes, this story is true
I can't make stuff like this up
