But the Delhi Police's slambang action had two serious fallouts. It alerted other IM members. As a result, many are
still at large. And it raised questions that made Muslims suspicious and angry. In Batla House, if you ask anyone about the encounter, they are all convinced it was fake, that Atif and Sajid were innocent, even though the IM group did not belong to the locality. What is worse, Muslims across the country see it as another instance of police highhandedness and brutality against their community.

Though I know "at large" means "generally".
