I was wrong count 8 and 10 are different. Count 8 is a (B)(1) and count 10 is a (B)(2).
This is an update b/c I went and read the statute at
Illinois General Assembly - Illinois Compiled Statutes
(720 ILCS 5/12-3.05) (was 720 ILCS 5/12-4)
Sec. 12-3.05. Aggravated battery. (then read down for sections b and 1)
(b) Offense based on injury to a child or person with an intellectual disability. A person who is at least 18 years of age commits aggravated battery when, in committing a battery, he or she knowingly and without legal justification by any means:
(1) causes great bodily harm or permanent disability or disfigurement to any child under the age of 13 years, or to any person with a severe or profound intellectual disability; or
(2) causes bodily harm or disability or disfigurement to any child under the age of 13 years or to any person with a severe or profound intellectual disability.
The difference appears to be that the (1) is permanent disability where the (2) is not.
