Navneet Kaur’s husband, Gurbal Singh, grew up in Rindge Towers in North Cambridge 2o years ago, back when it was a place to avoid — especially after dark.
The imposing towers near the Alewife MBTA station looked like two 20-story fortresses, betraying their origins as late-1960s subsidized housing. Security was pretty much nonexistent. The staff wasn’t known for its sensitivity to residents’ needs. Many of the tenants were counting the days until they could leave.
