At a rally outside Westminster Magistrates' Court this week, demonstrators turned out in large numbers to support Kneecap band member Liam Óg Ó hAnnaidh who was defending a terrorism charge for the alleged display of a Hezbollah flag at a gig last November.
Not everyone there were fans of Kneecap but all were eager to express solidarity with the people of Palestine.
Among those gathered, a woman from Cork who has lived in London for most of her life.
She spoke of how she stood in Parliament Square last week with a poster expressing support for the now proscribed terrorist group, Palestine Action.
"They can't arrest us all you know," she quipped. She chose not to bring the placard to the Kneecap demonstration.

More than 700 people have been arrested in recent weeks since the Palestine Action group was proscribed.
Many of them are aged over 60 and were arrested for holding up placards with "I oppose genocide, I support Palestine Action" written on them.
It's left people asking if the UK government has gone too far, not just because of the sheer amount of people that police have arrested but also because many feel that to equate support for Palestine Action with that of al-Qaeda or ISIS is wrong.
Proscription is 'intellectually bankrupt'
Peter Hain, a member of the House of Lords, served as secretary of state for Northern Ireland from 2005 to 2007.
He was recently among just three Labour Lords to vote against the proscription of Palestine Action as a terrorist group, describing it as "intellectually bankrupt, politically unprincipled and morally wrong".
During his contribution in the house, he spoke of the terror inflicted on people by groups such as the IRA.
"They are properly and rightly labelled terrorists," he told fellow members.
Mr Hain stressed that he didn't support the recent "criminal acts" at an RAF military base which Palestine Action members claimed responsibility for, and which led to the group's proscription.
However, he stressed that the arrest of people, such as an 83-year-old priest for holding up a "Private Eye cartoon" was "unjust" and "perverse".
"How have we got to the point where peacefully holding up a placard about the carnage in Gaza is equated with terrorism by al-Qaeda on 9/11 or Islamic State on countless occasions?
"Should not the police be concentrating on stopping real terrorism and real crime, not targeting peaceful protesters?", he asked.
A recent protest in Belfast, in support of Palestine Action, did not result in any arrests.
However, earlier this month a 74-year-old woman was arrested at an anti-racism rally in the city for wearing a Palestine Action t-shirt.
The Northern Ireland director of Amnesty International, Patrick Corrigan, wrote to PSNI Chief Constable Jon Boutcher afterwards telling him that "arresting people on terrorism offences for wearing a T-shirt is the height of absurdity".
Government under pressure
This week a new poll of Labour members indicated that 71% were opposed to the proscription of Palestine Action.
The survey was conducted by Survation for the Labour List website.
It came as the Home Secretary Yvette Cooper wrote an article for The Observer, defending her decision to ban Palestine Action.
"Some may think it is just a regular protest group known for occasional stunts. But that is not the extent of its past activities. Nor does it reflect disturbing information given to me that covered ideas and planning for future attacks," she wrote.
Ms Cooper told readers that the "clear advice and intelligence" given to her was that Palestine Action should be proscribed.
The Home Secretary also wrote that the group has been responsible for "intimidation, violence, weapons and serious injuries to individuals".
She insisted that people still had the right and freedom to protest against what is happening in Gaza and the government's response to it. However, she said that to express support for a proscribed organisation was different and would risk arrest.
Sally Rooney's support of Palestine Action
During a briefing with political journalists this week, Downing Street's spokesperson found themselves facing questions on whether the celebrated Irish author Sally Rooney should be arrested for donating proceeds of her work to Palestine Action.
Writing in The Irish Times last weekend, Ms Rooney explained that she receives residual fees from the BBC for adaptations of her books, 'Normal People' and 'Conversations with Friends'.
"I want to be clear that I intend to use these proceeds of my work, as well as my public platform generally, to go on supporting Palestine Action and direct action against genocide in whatever way I can," she wrote.
She also said that she would happily publish that statement in a British newspaper but "that would now be illegal".
The UK government's spokesperson insisted that he wouldn't comment specifically on Ms Rooney's comments, but added that "support for a proscribed organisation is an offence under the Terrorism Act and obviously the police will, as they have set out, implement the law within the law as you'd expect".
Legal challenge to proscription
Last month the cofounder of Palestine Action, Huda Ammori, was told by the High Court that the group had permission to challenge its proscription.
The judge ruled that the ban could conflict with the right to free speech and that the Home Secretary should have consulted with the group before proceeding with the ban.
That challenge is expected to proceed later this year.
There are some in Westminster who believe that an overturning of the ban could be a good thing, given that the government has faced significant criticism since it was implemented.
For others however, the conduct of Palestine Action has gone beyond the bounds of reasonable protest, and it is therefore in the interest of the UK that it remains banned.
