1) Don’t commit crimes.
2) Obey all police instructions.
By following these simple guidelines you’d be surprised how little trouble one runs into with the police, and, therefore, citizens are able to stay out of prison. I know that the subject is more nuanced and complicated than stated above, but on the other hand, I didn’t see any players protest when Black Lives Matters assassins were killing police officers and the then-president was hosting the BLM group at the White House as a sign of his support for the things they were doing. But simply from a consideration of self-preservation, have you never heard of killing the goose that lays the golden egg?
If you players don’t follow these simple guidelines and instead go ahead with your insistence on holding demonstrations during football games in November, which is just a boring repetition of your current kneeling in disrespect for America’s flag and our national anthem, then your disruptive practices will possibly destroy your own high-paying jobs with the NFL, and possibly destroy the NFL itself as the great entertainment and escape-vehicle it has become.
From here on out it’s up to you players. Consider carefully, because your multi-million dollar salaries are at stake.
