To date, there is no evidence of racism, just the allegation.
But race-baiters are on the ground in Ferguson in force, stoking the situation up to a nice bonfire.

Including Al Sharpton, Jesse Jackson, and the Trayvon Martin family's attorney, from the last manufactured racial hate-fest, giving a press conference today that there is basically no other explanation for what happened than full hard-on "racism".

Myself, I'll wait for results of the actual investigation.
