Bringing the discussion back to networking and away from gun issues, 
the question of liability for negligence in network operations is not 
new. There was discussion of this issue back when smurf attacks were 
common, networks were generally not doing ingress filtering (though 
many still are not) and many innocent third parties were being 
attacked (Schwab, Yahoo, others all in one week as I recall).

At the time there was concern over suing folks, though in many cases 
there was a strong case. Network operators continued to resist 
filtering despite being aware their own networks were being used to 
attack others. To my knowledge, BCP38 has not been cited in a court proceeding.

If you think it's OK to hold hosting providers at fault for 
negligence, network operators should be prepared to defend their own 
actions (or inaction) regarding any known or anticipated threats as well.
