Organizers of New York City's protests against police violence huddled on Sunday to explore fresh ways to keep people engaged in the struggle, mindful that the tide of demonstrators has ebbed over the last couple of days.

One plan was to take the demonstrations to the Barclays Center sports arena on Monday, where Britain's Prince William and his wife Kate will see the Brooklyn Nets basketball team play against the Cleveland Cavaliers.

Feeding off the media frenzy surrounding the royal visit is just one of the ideas that protest organizers, some of them students, discussed at the West-Park Presbyterian Church on Manhattan's wealthy Upper West Side neighborhood.
