If the players are protesting the mindless slaughter of young black men by “feared for my life” US LEO, how is that wrong? The judicial system does nothing about it. Juries are filled with childlike adults who are easily intimidated by people in authority.  

Philandro Castille did nothing. US LEO decided to kill him. For nothing.

Freddie Gray was killed in police custody in Baltimore. Rough ride, they showed him who is the master and who is the slave.
