The first line states "Police Community Support Officers are members of support staff", they are not police offices they are civilians, i.e. members of the public. They are employed by a police force as "support staff". The police officer who turned up in your example jumped in and pulled the kid out, he coped. Some of the members of the public there helped, the fishermen did, the PCSOs didn't. T
he PCSOs as members of the public in my opinion did not do their civic duty and try to save the kid and should hang their head in shame. You are confusing PCSOs as police officers, they are not.
