BALTIMORE - Among the hundreds marching in Baltimore in support of Freddie Gray was the Knicks' Carmelo Anthony, a Baltimore native.

"We're being heard. We've just got to be careful to do it the right way. We can't become violent ... we've got to be patient," Anthony said.

Violence escalated Monday after the funeral of Freddie Gray, who died of injuries while in police custody.
