Speaking as a computer security professional the entire second amendment argument is juvenile and stupid, if not harmful. On top of this we continue as a society to tolerate an obviously corrupt system of double standards. I completely agree with you.
We have corporations that now seem to operate under an entirely different set of lows than the rest of use do. We have HS and College kids being aggressively prosecuted for acts that cause tiny amounts of harm if any. Sony deploys a root-kit that puts the security of the systems of millions of customers in danger, and impairs those systems in general and they get basically asked to apologize and replace the defective product, they are not asked to do anything about the real damage. I don't recall prosecutors asking Aaron if he would like kindly remove his machine from MIT's wiring closet, delete the copies of the journals he made, tidy up and than forget the whole thing; no he was threatened with prison and a ruinous legal process until he killed himself. Yet for some reason Sony gets off without even having to clean up the mess they made.
Meanwhile the security community continues to want play army. Weather its with red vs blue rhetoric, or bizarre and ill considered Second Amendment analogies. To anything thinking person software it self and digital communications are more closely tied to the First Amendment, in terms of speech and anything you might do with a computer or network is more relate-able to expression or assembly.
A computer is not a weapon, let me repeat that a computer is not a weapon. Now it might control a weapon, be a component in or of a weapon but a computer it self is not a weapon. We don't need to conflate these things. By the logic they are using anything that can be weaponized is an arm. Which would mean I have the right to keep and bare well anything. "Sorry mister DEA agent, that brick of cocaine isn't drugs, I use it throw at people I don't like. Its a great arm, if you get hit with the corners of the package it really hurts; yet at only one kilo its light enough to carry around throw easily!" To say nothing of the implications for cars, kitchen knives etc.
This is about impotent little pricks that want to feel powerful, without having to leave their desks. The CFAA is a terrible law that is vague and potentially criminalizes lots of very innocent activity. Still I hardly think given the number of shared resources out there we want go to a total free for all where anyone can do anything the like online with no real/physical world consequences either. I am not even necessarily against "attack back" if its allowed under a prescribe limited set of circumstances, just like castle doctrines or stand your ground laws. The important parts of that though are "limited" and "prescribed" none of which applies to what Sony is doing here.
