>I dunno what you mean by suggesting crimes committed using computers are ambiguous. I mean the CFAA is vague and all, but more in an overly broad sense, which in this case seems to make it even less ambiguous.

Because the CFAA specifically only includes intentional hacks:

> ... having knowingly accessed a computer without authorization ...

>... intentionally accesses a computer without authorization ...

Of course, the typical retort is that being reckless is basically the same as "intentionally", but you'd need to jump through more hoops to prove what level of care is "reasonable".
