Cop without a Gun

I'm like Andy Griffith, I'm a cop without a gun.
Because of an accident, I carry a weight on my shoulders that feels like a ton.
I shot my sister with what I thought was a cap gun.
But it was real and I was horrified by what I had done.
The guilt nearly destroyed me, for years I cried myself to sleep.
When I think about that horrible tragedy, I still weep.
I became a cop to try to redeem myself for the horrible thing that I did.
My parents have hated me for years because I killed their youngest kid.
I will not carry a gun because of the damage that they do.
But I'm a dedicated cop who protects everybody, including you.

(Even though this poem is fictional, guns should always be kept out of the reach of children.)
