(2) The individual has not previously been convicted of a serious violent offense or sex offense as defined in RCW 9.94A.030; and

(3) Without regard to whether proof of any of these elements is required to convict, the individual is not currently charged with or convicted of an offense: (a) that is a sex offense; (b) that is a serious violent offense; (c) during which the individual used a firearm; or (d) during which the individual caused substantial or great bodily harm or death to another person.
