To give Tripeandonions links their appropriate context:
The first link is from November 2023 and the article describes the march covered by the article as having been "largely peaceful".
The second link is from February 2024. In a march attended by "tens of thousands", the article reports 12 arrests (not specifically connected with hate crimes).
The third article is from May 2021. The headline refers to 7 arrests for antisemitic offences, at a march attended by thousands.
Even one antisemitic incident is one too many. All hate crimes should be condemned, and I hope that all individuals engaging in such activities have been brought to justice.
None of these links refer to the event referenced in DomPom47's post.
All the links indicate lower or similar rates of offending behaviours when comparing with rates frequently encountered at mass protests and events. The recent city celebrations in Glasgow for Celtic winning the premier league had an attendance of around 25,000 and 19 arrests (so far - inquiries are still ongoing), for example.
