Thursday night a trio of groups will host a discussion of possible displacement of residents by the 2024 Olympics. The event, hosted by No Boston 2024, Black Lives Matter and the Boston Homeless Solidarity Committee, begins at 7 p.m. at Hope Central Church, 85 Seaverns Ave. Here's a link to the Facebook event page. Dubbed "Olympic Sized Displacement," the panel will explore whether Boston residents would be forced from their homes should Boston 2024 succeed in bringing the Olympics to the city. Organizers of the forum cite a 2007 study that found 2 million people had been displaced in the previous 20 years because of the Olympics.
