Police spotting (junction watch)

If you read it, you will see that PCSOs have the power (rather the designated power) to issue FPNs to cyclists for cyling on footpaths.

This is useful because I'm sure you see PCSOs enforcing red lights and so forth...

You can fuck with a PCSO by demanding to see their designated authority card, without which they have none...

Is this only for the extra designated powers or for any power above that of a citizen?
