This approach to sucking it and seeing is perfectly acceptable in terms of research. I've done it all my life...find the breaking point, know where the boundaries lie, and know when and how and if you can cross them. Makes 100% sense.
The only time it fails is when you know that the testing organisation may not have the "best interests" of the majority at heart. In this case, the "flexibility" of the "gov" to "make up it's mind as and when it sees fit" should raise adequate suspicion in everyone's mind.
Remember, they're there for their own ends; not ours: FACT. MP's expenses UK Scandal anyone? Easy jobs on the boards of companies that they've helped make international deals for and with ( defence etc )..
Keep it based in Reality :)
