Police in Glasgow issue a public appeal encouraging people to demonstrate lawfully during an anti-racism rally organised by Stand Up To Racism. The call comes as authorities prepare for large numbers expected to attend the event. Multiple reports say the message follows recent disorder in the city after a knife attack in Belfast on Tuesday night. Police do not describe the Belfast incident in detail in the provided summaries, but they link the timing of their appeal to concerns about public safety and maintaining order. The reports frame the forthcoming Glasgow demonstration as peaceful in intent, while stressing that participants should follow police instructions and legal protest rules. The overall coverage focuses on crowd expectations and the police request to prevent unrest, with the reminder that disorder can follow major incidents elsewhere. The outlets collectively highlight that authorities are preparing for the rally and want attendees to ensure the protest proceeds without violence or breaches of the law.
