To save myself some time I'm going to aggregate some of the Boston area scanner feeds that can be used to listen to police operations during protests in Boston. All of the Broadcastify feeds can be listened to on mobile using one of the many available scanner apps or the official Broadcastify app.
Full disclosure: I run two of these feeds and will note which ones.
Last updated 6/24/22.
Boston Police on Broadcastify (run by me)
All Boston Police District channels plus Citywide and Interagency Operations.

Boston Police Channel 1 on Broadcastify
Feed dedicated to BPD Channel 1, Citywide Events. This channel is sometimes activated during protests and other events.

Boston Police Channel 2 on Broadcastify
Feed dedicated to BPD Channel 2, Downtown/Chastwn/E. Boston (A-1/A-7).

Boston Police Channel 3 on Broadcastify
Feed dedicated to BPD Channel 3, Roxbury/Mattapan (B-2/B-3).

Boston Police Channel 4 on Broadcastify
Feed dedicated to BPD Channel 4, Jamaica Plain/Hyde Pk/W Roxbury/Roslindale /(E-5/E-13/E-18).

Boston Police Channel 5 on Broadcastify
Feed dedicated to BPD Channel 5, Back Bay/South End/Allston/Brighton (D-4/D-14).

Boston Police Channel 6 on Broadcastify
Feed dedicated to BPD Channel 5, S. Boston/Dorchester (C-6/C-11).

BAPERN Area Wide 4 on Broadcastify
Feed dedicated to BAPERN Area Wide 4. This is an interop channel that can be used by any BAPERN agency for wide area coverage. BPD has historically patched in Citywide Events so outside agencies can work with BPD. May not always be BPD.

BAPERN Central on Broadcastify
Feed dedicated to BAPERN Central. This is an interop channel used by BAPERN Central agencies to pass information between them. See https://www.snewiki.com/wiki/index.php/BAPERN for a list of BAPERN Central agencies.

MA State Police - Metro Boston Area on Broadcastify
Dispatch Talkgroups for Troops A and H, and Statewide. Geographically covering from the 495 belt area, into the heart of Boston. No longer includes SOPS.

MA State Police Troop H on Broadcastify
Dispatch Talkgroups for Troop H. See https://www.snewiki.com/wiki/index.php/Massachusetts_State_Police for more information on coverage.

Boston Area Special Event / Working Incident on Broadcastify (run by me)
This is the feed that I run and covers a variety of channels for use using wide area events. This replaces my Icecast feed as that was not mobile friendly and while missing a few channels it is much more mobile friendly. This is not up 100% of the time.
