Here's a terrible analogy, to explain to you why I think your reasoning is wrong:
When you play Russian Roulette, death for you is the MAXIMUM PENALTY.
So, your two options are to play Russian Roulette, or I'll bargain with you - you can give me $10,000.
"At no time did I ever seek - or even tell you that I intended to seek - death for you."
But your two choices were, to play Russian Roulette, or give me $10,000. I might even have accepted a counter-offer from you, say, $8,000.
Keep in mind, if you play Russian Roulette, it's up to the gun what really happens. You might just hear a loud CLICK. But limiting the maximum penalty to death, rather than for instance killing everyone you know and love, is there to prevent abuses.
I know it's a terrible analogy. I just want to point out that the statement, "At no time did this office ever seek – or ever tell Mr. Swartz’s attorneys that it intended to seek – maximum penalties under the law," that's a way of saying, "He had two choices, one, risk the maximum penalties, or two, bargain with us." That's a strong-arm bargaining tactic. Most people accept the plea bargain, but that doesn't mean the threat of maximum penalties wasn't made.
EDIT: As a prosecutor, her job is to put the gun on the table, load it with as many bullets as she can, and then get you to accept a plea. If Aaron had not accepted the plea, she would have done everything in her power to convict him of everything she could. Back to my analogy, there was more than one bullet in the gun - maybe 2, 3, 4, 5, or 6. A reasonable person would probably accept the plea - and that's up for debate, too. But for her to assert that "At no time did this office ever seek... maximum penalties under the law" is really deceptive / a lie.
