In reference to meeting targeting restrictions in effects, wouldn't you have to target someone who either has a penalty or a bonus?

Shameful Injury and targeting restrictions
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
No. Shameful Injury's Battle action's required target is: "a target Personality" (card text) with no restrictions, thus it can target any Personality at the current battlefield.
