As this is is a writing question, I suggest you try and make your own, but here is a brief example:
After reading the Bill of Rights, I know that I have the freedom of speech, religion, press, and the press in 2018 U.S. I also know that I have the right to own guns and much more. If I could change anything [you can put whatever but I'm picking something random], it would be so you have a right to bear arms but you can not get it as easy as today, as this could make it a little harder for shooting to happen.
Basically:
[Insert some of the bill of rights] [insert something I don't like that much] [insert what I would change and/or add]
I hope I helped!
