E is wrong because it would actually weaken the argument. By granting that sympathy from juries is a determinant in the conviction of different types of crimes, then we are removing the private vs public lawyer debate and now focusing on the juries' emotional reaction to the crimes. Moreover, we have no idea whether the public vs private lawyer groups can be divided into violent vs victimless crime. This is an extra layer that cannot be equated.
I hope this helps. Please let me know if you have any other questions or would like me to elaborate further.
