HOUSTON Several dozens gathered at Emancipation Park for a Black Lives More Than Matter rally Saturday. The gathering was one of several across Houston, part a growing movement to demand change. We want to reimagine policing and reallocating things, such as having maybe a mental health team, said organizer Dav Lewis. Were just trying to raise awareness and show people how voting can enact change and affect change in their community, said organizer Carl Ward. That is our message: Its really not just vote but be an informed voter.Organizers said a march to city hall will take place in the coming days.
