I'm wearing a wire

I'm wearing a wire that the cops strapped to my chest.
In a little while these scum bags will be under arrest.
My wife didn't want me to take the risk, she said it doesn't make sense.
But I have to do my part to get the evidence.

This man and his gang have killed before.
I'm going to make certain they don't kill anymore.
They want me to join their gang and I'm playing along.
When I get them to confess to murder, I will forever stop them from doing wrong.

I just asked the gang leader if it's true that they killed people who refused to pay protection money.
He said yes and he has the nerve to laugh because he thinks it's funny.
That's all the cops need, they just busted down the door.
The gang leader is trying to make a break for it but the police just knocked him to the floor.

The cops have cuffed them all and are taking them away.
I hope they get the death penalty or are locked up for the rest of their days.
I just did a great service for society.
Things will now be better because of me.
