Hamas: A Peace Loving Charity?

The Central Bank of Lebanon has begun a probe into the finances of Hamas. Hamas' response? Not an offer of cooperation; not an acceptance that as a charity their financial dealings should be open to review. No they label the probe as a "big mistake or a fatal mistake."

Doesn't sound like they're all too charitable to me. That sounds more like a threat, specifically a terroristic threat.

I'd like to hear Hamas try to reconcile this kind of threat with their position that they are a peace loving charity. I've never heard the Red Cross make veiled and not so veiled threats whenever their finances were probed. If there is nothing to hide, why the uproar?
