Sure. But if it turns out her allegations are correct, and the state was manipulating the data, I think that more than excuses it, and makes the police action malicious (criminal?) retaliation. If the state wasn't manipulating any data, then it's disorderly and improper (though doesn't call for armed officers still...).
Like most things, you have to sort out the details of the case before you can pronounce judgement.
Call me biased, but for some reason, when people sacrifice their careers and freedoms to send out a warning about corruption, I usually give them a lot more trust than the institution under scrutiny. Time will tell.
