Some photos from SF today (photos link to larger versions):
At Dolores Park at the start
Walking up Dolores Street, can't see the start of the march in front of me
...or the end of it behind me
At the rally at City Hall, DSA (in red and with red signs) marched up to the front shouting "do your job, abolish ICE" while state senator Scott Weiner (famous for his housing bill) spoke. Message seems a little misdirected imo, not a lot the California legislature can do to abolish ICE, but the state reps speaking endorsed their message
