It was stated in OOTP that Snape could read other people's minds just
like LV.  Then why is it that in the SS, when LV was sharing his body
with Quirrel, he didn't realize that Snape was faithful to Dumbledore?
And in the GOF when Barty Crouch Jr. was stealing boomslang skin,
lacewing flies and other ingredients to make Polyjuice Potion from
Snape, why did Snape suspect Harry of stealing them when he could just
read Harry's mind and figure out if it was really him all along who
was stealing?
