after they have just broken out from an angry group They were a group of women deliberately dressed in thin, armless bright red dresses talking over Hammond, demanding he reconsider the UK policy on climate control.
Not really dangerous... they seemed to have set out to make themselves look very distinctive (Handmaids etc) and with the style of dresses quite vulnerable and obviously not hiding anything.
They were irritating, obstructive but not violent, they didn't even seem angry, just loud and determined.
I am not saing she shouldn't have been stopped, but that his actions were disproportionately angry and aggressive.
