Smolarek and the detectives wear gloves at work every single day. She even wore gloves on the stand at trial.
So Smolarek knows that people who are experienced with the gloves or in a hurry, usually take them off inside out, but not always.
And she knows when you take the gloves off inside out, the fingertips are usually inside out, but not always.
Smolarek knows that it is impossible to tell which of these gloves were taken off inside out.
The ones with the thumb torn off could have been pulled straight off by an inexperienced person. But the pinky finger may be inside out.
The gloves that actually were in the ball, she never determined if they were inside or out or how many times they had been used or what.
So when Smolarek said she determined what was the inside for "wearer DNA" she lied.
And if she swabbed that visible stain and called it the outside and therefore the victim, she straight invented it.
Since she knew she invented it and that glove was probably inside out, and an excessive accumulation of blood would likely be Mulrenin touching himself, she lied.
