Woman I am really sorry that happened to you (just for attending a public meeting, FFS), that is awful. 
I think it’s important given there is so much video evidence for us all to try to make this event a line in the sand in terms of national policing and public debate about freedom of speech, debate, free assembly, public safety against authoritarian politics etc though. This is a completely one sided aggression. Has always been so.
Nothing was done to protect women in 2018 at Bristol jam jar venue either when masked protesters trapped them on a staircase.
Things must not be allowed to escalate like this.
This Brighton/Labour conference WPUK meeting needs discussion by Parliament to raise this national scandal with police and raise Parliamentary political understanding of what is happening, but also we needn’t to be raising it at the highest levels of policing nationally.
This describes the local complaint system via the relevant police force and what can be done at independent national level if it isn’t resolved satisfactorily: www.policeconduct.gov.uk/sites/default/files/Documents/Complaint_forms/A_guide_to_the_system.pdf
Hopefully WPUK are complaining, I don’t know about that, but individuals can too. Don’t forget to mention the protected characteristic of your sex in your complaint, and any others that you may have.
Also, fuck it, can WPUK and any individuals who want to please write to Liberty and any other groups that claim to protect free speech and free assembly and ask them to take campaigning action on this?
Yes they have jumped the TRA gender politics shark and won’t accept what a woman is, but these organisations can’t maintain a public facade of being on the side of justice and freedom (and also keep their charitable status for the purpose of public benefit, if they are a charity)... and also at the same time: pick and choose on the basis of agreeing with genderist politics or not, which cases of abuse against freedom of speech, free thought, free assembly, etc are going to be defended by them and which other cases of abuse against those things are just fine to be left completely undefended by the state or the third sector.
It’s completely unacceptable that policy/regulatory capture leaves women and children undefended by our national institutions especially when we fund a lot of these through our taxes. These are ours just as much as anyone elses’.
Women should not have to try to reinvent all of our national institutions because they have decided to go for misogynistic gender politics, and neither is that feasible as a tactic if women want to see change in our own or our grandkids’ lifetimes.
The law is still on our side and knows what a woman is, self ID is not yet here completely, so while we retain those protections let’s try to get the institutions that we have, to do what they are there for.
I will be writing to my MP who is Labour to ask them to condemn this attack on women’s free speech assembly and to ask my MP to write with their concerns to:
the Minister of State for Crime, Policing and the Fire Service, who is Kit Malthouse MP whose brief includes police training and resourcing
Parliamentary Under Secretary of State for Crime, Safeguarding, and Vulnerability who is Victoria Atkins MP whose brief includes VAWG and crime prevention.
Also The Baroness (Susan) Williams of Trafford, Minister of State for Countering Extremism, and Minister of State for Equalities, whose brief covers hate crime (important that the Lords are aware of these issues too).
And finally copying in Priti Patel, the Secretary of State at the Home Office who
Has overall responsibility for all of these areas.
You can find out more about their responsibilities here: en.m.wikipedia.org/wiki/Home_Office
Some people may not agree with this but I’m also going to mention the widespread acknowledgment that police funding has plummeted with inevitable consequences for training and resourcing and that these cuts need to be reversed for public safety:
