Answer:
I can be heard in a court or carried with you.
I ask no questions but receive a lot of answers. What am I?
In Paris but not in France the thinnest of its siblings.
I go around in circles, but always straight ahead, never complain, no matter where I am led.
The more you have me the less you see. Shine a light on me and I shall flee.
