Emotions are running high across the country in the days since George Zimmerman was found not guilty in the death of Trayvon Martin.

Relatively peaceful protests happened overnight while some turned into violence.

“There was great concern about violence breaking out here and other cities across the country,” CNN's Miguel Marquez reports from Los Angeles. “Police have drawn a line in the sand here, and it seems to be holding for now.”

Meanwhile,  Anderson Cooper's exclusive interview with Juror B37 sparked reaction from four of the other jurors.

They released a statement saying, “Serving on this jury has been highly emotional and physically draining experience for each of us. The death of a teenager weighed heavily on our hearts but in the end we did what the law required us to do.” (watch top video)

The discontent and frustration over the law leading to the “not guilty” verdict has reached Washington, DC.

Attorney General Eric Holder spoke out against the nation's "Stand Your Ground" laws cited in the Zimmerman trial, telling the NAACP “laws that senselessly expand the concept of self-defense and sow dangerous conflict in our neighborhoods.” Watch:

“The attorney general is pledging a full investigation, but he's being very careful not to promise what the results will be,” CNN's Dan Lothian reports from the White House.

While the Obama administration faces pressure to file hate crime charges, the politics of the verdict is much more complex.

CNN's Chief Political Analyst Gloria Borger says there is not much the Justice Department could do because this is a state issue and not a federal issue, and it would be very difficult. Watch:

“There's a really high bar for the Justice Department to do this,” Borger says. “You would actually have to prove intent, that Zimmerman shot Trayvon Martin because he was black…That was not a part of the case.”
