I Killed A Gangster

Until 1934 I was a barber, that used to be my profession.
Many people are suffering because of this Great Depression.
A Gangster walked into my shop but when he left, he had to be carried.
He was responsible for many deaths and I made sure that he was buried.
I usually don't brag but this time I love to gloat.
That punk asked for a shave and I slit his throat.
He dealt in Prostitution, Gambling, Booze and Heroin.
I made sure that he couldn't do anything illegal again.
I'm not ashamed of myself even though I lost my freedom and my wife.
I saved people from that animal and a judge sentenced me to life.
I'll be locked up for the remainder of my years.
I don't regret what I did, my conscience is clear.

(This fictional poem takes place in the 1930s.)
