Federal police are still looking into a motive for this weekend’s mass shooting at a Sikh temple in Wisconsin. Authorities suspect that 40 year-old Wade Michael Page belonged to a white supremacist group known as the National Alliance. Sikh and other religious minority groups say they’ve had to combat years of post-9/11 violence and harassment against their members. Pacifica KPFK’s Ernesto Arce has more from Los Angeles.
