Not only is this NOT true restitution, if it couldn't be used in the DP trial, that might not bode well for Amy either.
Since Amy could not have known about the check fraud situation until she returned from P.R. - the same night KC was actually arrested, she can't be used as a SODDI defense for "retribution" for missing funds. In fact, restitution of Amy's money could have been a strategy to make it EASIER for the defense to mention her as a possible SODDI suspect if the theft could not be mentioned in court if it was deemed "settled".
I think shortly after KC was arrested and, although her family corroborated her fake "nanny" story, she realized (as did her family) that they needed to broaden the database of possible "nanny" suspects so they were not limited to ZFG, which was problematic at best. Amy and Jesse have certainly been individuals amongst many of these. I think at this point people would be scared to admit they'd even known her; it might require lawyering up and involve lots of time and money.
There is no way that Amy can be "compensated" for the betrayal and lies, mental anguish and subsequent legal representation on her own behalf that KC has subjected her to with a silly little check that covers the dollar amount she was defrauded.
KC made a point of trying to implicate anyone that might now have a grudge against her (as when she told Rob D to "get some dirt" on Kiomarie to impeach her testimony.
I think what has shocked most of us even more than the entitlement attitude all of the Anthonys have exhibited, is the fact that JB has gotten by with as much sleazy stuff as he has in delaying this trial and blaming everyone else for problems his own client started.
