An image of Boston Police Captain Haseeb Hosein, the commander of the B-3 district covering Mattapan and parts of Dorchester, is projected on the side of a building in Boston as part of the Boston #StandwithImmigrants photo exhibition, created by Erik Jacobs. The subjects of the exhibit will be part of a moderated program tonight (May 3) at the Edward M. Kennedy Institute for the United States Senate in Dorchester. A short reception (6 p.m.) will precede the program. Through the end of May 2018, the Institute is dedicating a digital exhibit space to showcase the project’s powerful imagery, enabling visitors and students from across the country to learn about the experiences of immigrants from throughout Boston.
