Obama Calls for Calm After George Zimmerman Verdict

Race riots are one horror he hasn't befell on America yet

President Barack Obama called for calm on Sunday after the acquittal of George Zimmerman in the shooting death of unarmed black teenager Trayvon Martin, as thousands of civil rights demonstrators turned out at rallies to condemn racial profiling.

Zimmerman, cleared late on Saturday by a Florida jury of six women, still faces public outrage, a possible civil suit and demands for a federal investigation.
