Pop is essentially asking why two armed men were afraid of a child. The question implies that their fear was irrational and thus undermines Officer Moore justifying shooting Jerome by insisting he was afraid. Black Lives Matter is a social movement that coalesced around the killings of several unarmed Black children and young adults killed by authorities, including Trayvon Martin, Michael Brown, and Tamir Rice. When an attendee at the hearing shouts, “Black lives matter!”, it indicates that the public sees Jerome’s shooting as another example of law enforcement killing Black boys due to racist biases. Grandma’s assertion that Jerome was a “good boy” suggests she’s afraid that people may try to blame 12-year-old Jerome for his killing by painting him as a budding criminal, which occurred in the case of Michael Brown.
