It really doesn't. A quick summary for the press does not constitute "it all", I don't know what to tell ya.
Here's the thing you seem to be completely missing out on. Whatever she did, it deserves a fitting punishment. HEAVY emphasis on fitting. If she would have to go to jail for a couple of months or whatever, and that would have been that, then that would be completely fine. But that's not what would happen. The entire career she worked for, while being a completely upstanding citizen, for YEARS would be basically down the drain. That is not a fitting punishment. I'm sure that if the crime would have been more severe (and this is where the severity thing comes in by the way, which in fact is relevant), like maybe she stabbed the guy multiple times, or he's now an invalid due to her attack, then maybe the judge would have found it more prudent to put her into prison, regardless of the consequences.
And yeah, she's rich, white, a pretty girl, privileged, whatever. And maybe it's unfair towards you and all poor people and minorities that she's treated more correctly than them. In fact, it is unfair. But that doesn't mean that she needs to be treated unfairly, and have her life completely altered due to a single mistake. That seems incredibly and utterly vindictive of you, and not just or even-handed in the slightest. I feel lame for going there, but what if she were a minority? Would you have even questioned it?
Besides, she's not your enemy. She seems to be working towards something to aid society in some sort of measurable way. Her and her situation is not the thing you should be getting up in arms about.
