I actually really liked Diana's part in this issue. Her raid of the prisoner holding facility essentially sent two messages. First message was that if the government was going pull something like abducting Clark's friends in some shadowy op, she wasn't going to stand for it. She has the power to do something about a violation like that and she will, without hesitation. The second message was that they are willing to work with the government, if done properly, and have nothing to hide. Clark is a good man. Diana knows it. Clark's friends know it. They all have nothing to hide. Diana also knew that ARGUS would keep coming after everyone until they were satisfied, so she was helping things along. When it comes to Clark's friends, I think Diana wanted to help them work through the shock of finding out Clark is Superman. So using the lasso to provide some clarity and insight into how they really feel would benefit them. It may help them come to terms with what they learned so that they can rebuild a relationship with Clark. Really, Diana stuck her neck out to help everyone involved and offered up a solution that would satisfy everyone. She also made it clear what she wasn't going to put up with. I thought it was a pretty great moment for her.
