e.g. the people being arrested for silent praying (wasn't it just two people?) were breaching specific PSPOs that are specifically designed to provide a safe buffer zone around abortion clinics so that people can receive their health services (i.e. abortion and related services) without fear of being harassed. By stating "silent praying", you make it look as thought they weren't being deliberately provocative in order to make a protest - the exact type of thing that the PSPO is designed to protect against.
