The courts jailed seven young people on Friday who had taken part in the protests against the Israeli assault on Gaza.
Aged between 17 and 25, the defendants had all pleaded guilty to charges of violent disorder at previous court hearings.
Another three cases were delayed for the preparation of pre-sentence reports by the probation service.
The judge claimed that sentences must act as a “deterrence” to other people intent on committing violent disorder.
Sentences were as high as two and a half years in prison.
The police relied heavily on CCTV evidence, with many of the accused tracked by police intelligence teams on the demonstration and arrested later.
Two of the defendants were arrested in May, in their homes in the early hours of the morning.
In one such arrest, police handcuffed the sister of one of the defendants and her husband for an hour while they searched the house and confiscated clothes and her laptop.
The sister of another defendant said, “I’ll never go on a protest again”.
Judge Denniss called the police response on the demonstrations “measured”.
Socialist Worker will be finding the addresses of all the people who have been sent to prison and will publish them so that everyone can send messages of solidarity.
