We fly our flag at half-staff for those who lose their lives in the line of duty, whether law enforcement or military or in the political arena.
Why not for every single veteran who commits suicide after having found out that war was more than what is depicted in movies and video games?
Why not for those homeless who die of neglect in alleyways? Why not for those who continue to be murdered in racially motivated hate crimes? Why not for those who die in various situations brought on by prescription overdoses in the name of big pharmaceutical profits?
