This has been explained many times.
The Bill of Rights tells the GOVERNMENT, I'll repeat that, the GOVERNMENT what not to do to certain people.
It doesn't apply to every human being on US Soil, as Barr said. This is simple. It doesn't apply to Chinese reporters who attempt to freely express joy under the 1st Amendment. They end up without any protection under the first amendment, which is the first of the first 10 Amendments, which are known as the Bill of Rights, which Barr referred to in his statement.
Now lets see if that jackhammer can get through that lump of granite sitting on your shoulders.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise by certain people thereof; or abridging the freedom of speech of certain people, or of the press; or the right of the certain people peaceably to assemble, and to petition the government for a redress of grievances.
