Match-Pump Approach

Hypocrisy or a hypocritical way of doing things. You cause some bad problems to occur, while making sure that nobody knows that you are the cause of them, and then come up solutions to them so that you will be seen as as a saviour by all around you, as if you set fire on something with a match yourself and pumped water onto it as a hero citizen, pretending that you happen to be there.

"I suspect it was John who made the car tyre flat, just before our driving trip last week. He did that probably so that he could come to the rescue in his car and impress all the girls like a hero. What a match-pump approach that was!"
