I wonder if these same people would have supported federal charges against OJ Simpson?

Via WaPo:

. . . Some of the reaction to the trial — among both blacks and whites — stems from wildly different views of the role of race in the criminal justice system more broadly. Fully 86 percent of African Americans say blacks and other minorities do not get equal treatment under the law; the number of whites saying so is less than half as large, 41 percent. A majority of whites, 54 percent, say there is equal treatment for minority groups.

About eight in 10 African Americans (81 percent) say the federal government should charge Zimmerman in federal court with civil rights violations. Just 27 percent of whites agree, while 59 percent say the government should not bring such charges.
