There's no "injury" here that could ever serve as the basis for a criminal prosecution.
But I think it could be said that injury was clearly their intent. They darn sure did not call and RECORD it because they hoped to show everyone what a great guy Gov. Walker was.
And about the “one party awareness in Wisconsin and New York - it would seem only to protect/serve the person who is doing the recording. I understand there are cases where someone NEEDS to have evidence of threatening or abusive language, when recording without permission would serve this end, but IMHO this does not fall under that classification. If anything, this could be seen as entrapment.
May God give us strength.
