Some people just like playing "let's be Mr Plod". Ignore them.
I assume you mean the segregated bit of cycle path on the pavement, not the cycle lane marked off with a dotted line on the carriageway! That last looks well dodgy to tackle contraflow! (or any-flow, for that matter).
Same type of people that say "you're not the police" to helmet camera users...
