Do these players even know what it is they are protesting?  Capernick started a protest about the disproportionate number of blacks incarcerated in American prisons.  Maybe he doesn't realize that the number of people (regardless of race) in prison is based upon the number of people convicted of crimes.  Wouldn't it be a better effort to try to make it so less crimes are committed?  Protesting a sad fact seems awful hollow, it is like protesting that there is too much rain in Washington.  Even worse, protesting that certain people should not go to jail would seem to encourage those people in their criminal pursuits because famous athletes "feel" for them.
