You're wrong

It sounds untrustworthy the way I speak
Now my eyes are hidden you can’t see
But I'm watching you moving around

I was walking freely, carrying with me
A harmonica in the key of C
I was there in the corner
When the cop gave me an order
Screaming unnecessarily

This is not what you think
It is just an instrument, but I knew it was too late

Down down down, put your gun down, he said
Sir, you have to calm down and put your hands on your head
And then people came and started pointing fingers at me
Saying: I don't know what you have done boy
All I know is you’re wrong!

Are you uncomfortable with me?
'Cause you’re walking quickly
If I had the superpower of invisibility
I know I would finally be safe here
