A large protest was held in Bristol UK repression of protests and the
plans to restrict them more. The protesters attacked cops violently and
injured some severely.
Bristol is a rather leftish city which elects a Green representative
to Parliament, so it makes sense that a big protest would happen there,
and that local officials would support the purpose.
I expect the violence did harm to the cause of defending the right to
protest, because it will allow the cops (who did not, it seems, act
like thugs on this occasion) a justification for the claim they need
more powers — which would enable the to repress nonviolent protests
more in the future,
It is not a valid justification, but they will make use of it anyway.
The left needs to adopt disciplined nonviolence, such as it employed
effectively in the 60s and 70s in the US, and reject "black bloc"
tactics. As long as it does not, it is vulnerable both to hot-headded
supporters and to right-wing provocateurs.
