Seems not just 1 isolated violent representative with a sledgehammer, others also had them.
"Each of the group was armed with a sledgehammer, Heer told the jury. While the implements were intended to be used to damage property, the defendants had also been prepared to deploy them as “weapons” against people if necessary, she said.
“The evidence demonstrates that all of these defendants used them for that purpose — to threaten or to attack the security guards and to lend support to one another as they did so”.
She added: “When the police arrived, as the defendants knew they would, Samuel Corner attacked them, going so far as to strike a female officer across the back with his sledgehammer while she was on the floor, facing away from him.”
The footage was taken from CCTV in the factory and nearby buildings, as well as cameras worn by security and police. Some of the clips were recorded by the alleged members of Palestine Action themselves and were taken from their devices after their arrest.
One of the clips shows a security guard, armed only with an umbrella, appearing to retreat as three figures approach him. Another clip shows a security guard with blood over his face."
Its captured on CCTV and bodycam so easily shown in court.
