EFF's Part 3 said "punishment should fit the crime."
"Computer crime law should not double-count offenses." CFAA's section 1030(a)(3) criminalizes accessing without authorization either:
(a) computers used exclusively by the federal government or
(b) ones used by the government in ways that affect its computer use.
Section 1030(a)(4) criminalizes "knowingly and with intent to defraud" computer accessing without authorization and/or obtaining something of value as a result.
CFAA criminalizes this behavior elsewhere in the statute. Section 1030(2)(2)(B) criminalizes accessing computer systems without authorization and obtaining information from a US agency or department.
It also prohibits accessing without authorization any "protected computer." The ill-defined term invites abuse. It can mean any government operated one.
Conduct prohibited under section 1030(a)(4) is redundant. It's covered under the wire fraud statute (18 USC 1343). It criminalizes wire communications for fraudulent schemes.
