I was riding in Hong Kong from Causeway Bay towards Wanchai one day in order to do a U-turn back towards the Cross-Harbour Tunnel (always wondered why I have to go that far when the tunnel is actually almost at my doorstep but well...)

I was following a cop rider and there, right in front of me, he crossed a double continuous lane to ride left onto the flyover that leads to the tunnel.

Alright then, I do the same and follow him. Sure enough, he stops his sad overweight bike on the flyover and makes a sign for me to stop. So I do.

Cop: "Hey Sir, you've crossed a double line ! Show me your licence."

Me: "Hey Sir, you've crossed a double line before me ! Show me your licence first !"

Cop (laughing): "But I'm a policeman on duty ! I can cross double lines ! So show me your licence."

Me (laughing): "Yes, sure you can, but you've got to have your blinking blue lights on ! Let me take your number."

Cop (not laughing anymore): "Alright then. You may go."

So I guess, learn your rights coz it felt so good ! :))
