It is real easy to blame the Navy for 37 whales grounding themselves on the east coast when an exercise was going on 100 miles away. There was no proof that the active sonar killed these things but the Navy, and the military in general, is always the scapegoat for environmentalists if any exercise occurs within the vicinity when an animal dies.
From the lawyer of the tree huggers:
NRDC attorney Joel Reynolds said the group recognizes the Navy's need to detect enemies, and he noted that the lawsuit seeks limits on sonar during training exercises, not in war.
Hey asshole, how the fuck are we supposed to train for war when you cut our dicks off in peacetime?
Eh, here is the reality- the Navy ships and submarines will use active whenever the fuck they feel like it, especially the subs, because there is no way of civilians knowing, outside of having your head dunked underwater when an exercise is going on, when the military is using active sonar out there.
