Instead of a rifle, how about a shotgun? It fires a nice wide spread shot p=
attern. I think you would be much more likely to do some damage (ie: knock =
fiber off a pole) with something like that. Here in New Jersey it is illega=
l to use a rifle to hunt deer, so typically you will find hunters using a b=
ow/arrow or Shotgun and you will see a lot of road signs (or other abandon =
junk) that has been victim of a shotgun blast.

Back in my ISP days it was more common for people to take pot shots at
remote equipment cabinets than the cable/fiber itself. Any field
enclosure is as easy a target as your average bullet-ridden road sign.
Although this was extremely rare; I can only recall one instance where
it was the direct cause of an outage.
