A crowd of demonstrators marching in New York was videoed as they repeated antiphonal chants. Some listeners thought they were saying
"What do we want?" "Dead Cops"
"When do we want it?" "Now"
Other listeners, including and radio talk show host Thom Hartman claim that they did not hear it that way.
I was contacted by Tasneem Nasrulla, a correspondent for online new service BuzzFeed, who asked that I resolve the issue. I applied filtering techniques to reduce the background sounds in order to make the chant clear. You can hear the filtered clear version of the chants here:
