It’s just the natural state of capitalism. Regulation can keep it in check, but regulation will eventually falter, then fail due to regulatory capture and weakening of safeguards by politicians sympathetic to capital (read: bribed by).

You’re doing a lot of mental gymnastics to make this make sense from an accidental perspective. You’ve made up your mind that it was a mistaken intruder.

Me, personally? I have no clue whether he did or didn’t. And considering only he can know that for sure, I think that’s the only reasonable conclusion you can draw.

I certainly have no interest in debating all of these hypothetical motives he could have had.

1. Easy excuse to make, hard to rebut.

2. You don’t need a motive, it just helps and could have helped cast doubt on #1.

3. If there’s no reason to risk it if you’re trying to murder your girlfriend there’s no reason to risk it against an attacker.

I don’t really care about this case all that much. All of the unknowns make it confounding more than interesting.
