For example, some graffiti was discovered in the Philadelphia suburbs with the message "Kill Zimmerman". And this is just a drop in the bucket.
Incidents like this will only fuel the right-wing media's sensationalistic speculation about violent race wars in the wake of Saturday's verdict. And these incidents only make the perpetrators look no better than Zimmerman.
Violence and property damage will not change the verdict, nor will they bring Trayvon Martin back to life.
Those of us who feel that justice was not served will get our message across most clearly if we do so in a reasonable, peaceful, and dignified way. I think that's surely what Trayvon's parents - both of them the embodiment of grace and class - would want.
