Correct on suing the bejeesus out of the lamestream media for portraying him as a racist white cracka stalker.
Incorrect on writing the book, IMO. That will simply invite the prosecution, feds, race baiters, etc.. to look for any inconsistency between his book and his previous public statements to press Perjury (or other) charges against him.
At this point, the less Zimmerman says the better -- again IMO. YMMV.
Lawsuits against NBC and CNN - yes.
Book deal - no.
That’s actually a very astute course of action.
