Any Word smiths out there?

I'm looking for a word or short conscience phrase (sound bite?) to describe a particular stunt used to manipulate attention from bystanders (creating the false perception he's in need of assistance/protection). Hoping I can find someone who can describe this particular performance more eloquently than I can.

This particular person will respond to being caught out lying by sitting, acting helpless, waving his arms (normally he does not "talk with his hands") & repeatedly opening and closing his mouth (reminds me of a fish gasping for air). The aim is twofold

1/ if he doesn't actually say anything, he's not admitting fault/guilt.

2/ the performance manipulates bystanders to gain sympathy, backing or support. Thus creating a useful distraction as well as manufacturing a potential protector.
