Sarah Palin believes her stalker still poses a very serious threat ... and now she's begging a judge to NOT lift the restraining order against him because she's afraid he'll attack her family.
Sarah just filed new legal documents in Alaska ... in which she explains how she and her BFF Kristan Cole are "fearful" of what could happen if Shawn Christy is allowed to travel to Alaska ... as he claims he intends to do in the near future.
The papers were filed in response to Christy's recent attempts to dissolve the restraining order that was placed against him in October after several "threatening messages" geared towards Sarah surfaced online.
Now, Sarah claims she is still scared -- insisting Christy has continued to demonstrate "menacing behavior" and "poses a risk of serious physical harm or injury to Ms. Cole and the Palins."
As we previously reported, Christy -- who lives in Pennsylvania -- believes Sarah randomly began to send him "ominous" text messages last year ... despite the fact they've never met.
The judge is expected to make a ruling on the matter in the next few days.
