why would rashad question the sincerity of chief killabrews card? is rashad justified in doing so ?

Rashad wonders if the creed is supposed to make him feel guilty for his eleged "wrongdoing", or if it is supposed to make him feel that he is still a part of something bigger. Unlike his father's relationship with the military, Rashad feels uncomfortable about the connections between ROTC, the military, and the police.
