Two separate investigations are underway into several Boston Police officers after clips of body camera footage went public that appeared to show them shoving, pepper spraying and using batons on demonstrators during a protest against police brutality this spring. The clips were first published on Friday by online news outlet The Appeal. The attorney who was sent the nearly 70 hours of footage as part of his legal case defending some of those protesters, Carl Williams, has since given it to GBH News as well, and he joined Jim Braude to discuss.
