1. We have GOT to close some of these loopholes now that we know what they are and…
2. Someone should go to federal prison for this leak
We can’t undo what we now know about avoiding taxes and we cannot condone egregious invasions of privacy like this.
I also don't believe Snowden deserves to be in jail (or rather that he should be pardoned). Sometimes you can't fix things without breaking the law - everyone does it on a daily basis with few consequences (jaywalking, etc). Sometimes it has to be done on a larger scale in order to shed light on injustices - otherwise the power of the few will prevail over the power of the many.
I understand that the word "If" is doing a lot a work in that sentence, and I have some sympathy for law-abiding billionaires who don't deserve to have their privacy invaded, but they should receive some form of compensation rather than legal punishment of the leaker.
