Sharpton called for what he termed "Occupy Corners" rallies at locations where violence is prevalent.
He was joined by Shianne Norman, whose 4-year old son Lloyd Morgan Jr. was the victim of one of the most recent shootings.
The boy was shot in the head and killed by a stray bullet in the Morrisania section of the Bronx July 22.
The NYPD made a third arrest in the case Friday, of 19-year old Ronald Jeffrey.
The toddler's death, the murder of a 14-year old in Baychester Thursday night, and dozens of other summer shootings, have fueled the flames on the public debate over the NYPD's Stop and Frisk program - and how much community leaders are doing to stop the violence.
Now Sharpton has launched his "Occupy Corners" effort.
"I want to spread a climate in our community, so that young people say, 'What are they doing out there every weekend?' They're out there because of the guns."
Sharpton says the issue runs deeper than gun control, and stop and frisk.
"Yes, a lot of guns are coming from the South, but the South is not having this type of behavior because there's a different presence there from the community and the police and the correlation between the two," Sharpton said.
At a community fair in Crotona Park East, State Assemblyman Eric Stevenson called for reform of stop and frisk, and said he'd support Sharpton's movement.
"I would agree with that, and I think that's what we're going to have to do," said Stevenson. "We're going to have to take the streets back into our own hands."
