(CNN) -

One day before thousands are expected to gather for the funeral of Michael Brown, political and civil rights leaders don't appear ready to let the moment pass. On the Sunday political talk shows, many called for conversations about the relationship between law enforcement and minority citizens as well as a long, hard look at the tactical gear offered to local police after 9/11.

"There needs to be a frank discussion about how we change the way the African American community is policed," Rep. William Lacy Clay, the Democrat who represents the Ferguson community in Congress, told CBS' "Face the Nation" Sunday. "These people were sworn to serve and protect. And apparently that is not happening here. And so we have to change that dynamic."

Brown, an 18-year-old African American, was shot and killed by a white police officer on August 9 in Ferguson, Missouri, under circumstances that, while still subject to several investigations, sparked immediate outcry. The racially-charged optics of the shooting, coupled with what some in the community say are long-simmering racial tensions in the area, sparked weeks of sometimes-violent protests.

Upset community members demanded that they be heard as they protested, police bore down to maintain order and canisters of tear gas ricocheted off the pavement in Ferguson, stirring emotions across the United States. By the end of last week, President Barack Obama had interrupted his time away from Washington twice to address the situation from his Martha's Vineyard vacation.

Brown's funeral, which will feature a eulogy by the Rev. Al Sharpton, comes as tensions appear to have eased in Ferguson. Sharpton, who praised what he said was an even-handed, appropriate response by Obama, said he'll speak Monday about how to build on the message of the nonviolent protesters.

"My message is that we've got to turn this moment into a movement," Sharpton said. "We cannot be anti-police. We cannot be violent. But we cannot duck what history is called upon."

Sharpton said there is also a critical place for potential 2016 presidential contenders like Jeb Bush and Hillary Clinton, as well as prominent leaders like former President Bill Clinton, in any national discussion arising from Brown's death.

"It would seem to me, if you are seeking the highest office, we ought to have some idea what you would do in the higher office during this time," Sharpton said. "They need to address racial profiling. They need to address the continued disproportionate amount of young blacks, particularly young black males, killed by police. They need to deal with the militarization of policing. They need to deal with this idea of low-level crimes being dealt with with aggressive policing."

Kentucky Sen. Rand Paul, who is considering a bid for the 2016 Republican presidential nomination, told NBC's "Meet the Press" the police response to protests in Ferguson was questionable.

"Let's say none of this has to do with race. It might not," Paul said. "But the belief -- if you're African-American and you live in Ferguson -- the belief is you see the people in prison and they're mostly black and brown, that somehow it is racial even if the thoughts that were going on at that time had nothing to do with race."
