My heart is broken for Trayvon Martin's family and terrified about what Zimmerman and his ilk will do now that he/they truly know that they can still get away with this sort of thing, even when they are caught.
As a mother of daughters, I have known the fear and humiliation involved in having to educate my daughters to try to protect themselves as best as they can from our predatory rape culture, but I know that is nothing - nothing - compared to the fear experienced by the parents of African-American male children who must be taught a host of protective behaviors to survive on a daily basis in our racist society. I ache for the mothers. I am so sorry that so many children have been raised to injure theirs.
There will never be enough goodness in us to exonerate all this.
