National Action Network and Rev. Al Sharpton, responding to the recent rash of shootings that have plagued the country, will kick off the Occupy the Corners effort tonight for four consecutive weekends from 11 p.m. to 1 a.m. Each weekend, NAN and community activists, politicians, church leaders, and the like, will stand on corners in "hotspot" areas throughout the city, watching for any signs of violence, talking to residents, and take back the streets.
