It's appalling that your criticism of Timothy McVeigh is that he wasn't enough like Osama bin Laden. Do you really think either one of these should serve as a model?
(Shrug) bin Laden got shit done. McVeigh did not.
They both ended up exactly where they deserved, but you can't ignore the fact that one of them was an effective political strategist while the other one was nothing but a plain old mass murderer.
To the extent that bin Laden's ultimate goal was to cause severe financial damage to US interests, there's no question but that he succeeded grandly. Sure, 99% of the damage that resulted from 9/11 was self-inflicted by the Bush administration, but the outcome was the same as if bin Laden had destroyed trillions of dollars in US wealth himself.
That's the lesson of Timothy McVeigh: if blowing up an entire building full of your opponents has no effect, then writing a stern letter to your Congressman is laughable.
As far as bin Laden being a good role model, he won didn't he? He got inside Washinton, D.C.'s decision loop and systematically turned it against its own interests. Trillions wasted on war, distracted from fixing economic problems, Turkey handed to the mullahs on a silver platter, occupation of ungovernable territories, etc.
Hyperbolic much?
Second, that you think calling the poster a "loser" is important is telling. What do you think that will accomplish? Has insulting people ever won them over to your position, in your experience? Or were you banking on everyone's agreement, effectively forcing an internet shaming?
Nobody has ever won against Washington, D.C. by scoring a symbolic personal victory against a few minions. Even if you are like McVeigh and willing to accept a certain degree of collateral damage, it has no effect. It turns out that blowing up a Federal building is the political equivalent of putting itching powder in Uncle Sam's shorts.
So if that is the case, sending an outspoken email is a pre-defeated strategy. It is the action of someone who lost before they started, a loser.
What? McVeigh murdered innocent people. The parent is proposing investigating the prosecutor for breaching the mores and laws that govern her profession using the legal system already in place. These are not exactly equivalent.
I have no interest in defeating Washington, D.C. I have no desire to "win" if "winning" requires me thinking "like Osama Bin Ladin" (or do you mean not thinking? because I think he's dead, last time I checked).
There's no worse fear for a bureaucrat than to be hoisted by their own petard, to face a misconduct investigation, and possibly criminal and civil charges. A lot of harm can be prevented if her public service career is ended early on the count of what she has done to Aaron (and presumably others): I'd rather her career end as an associate in a think-tank (or whatever), rather than as the next Rudy Giuliani (who also started his career as a DA).
This is Timothy McVeigh thinking, and it makes you a loser just like it did to McVeigh. You can never kill or destroy enough people to defeat Washington, D.C.
To win you have to think like Osama bin Laden: turn the system against itself. Wholesale, not retail. Scale up, not one off. TSA, not EFF.
