Before anyone "flames" away at my post
In my "previous life"
I did some "diving" in the Army (deepest dive was 280', decompression of course), and in cilvilian life am a certified divemaster (which includes search and resuce/recovery).
Consider myself a "decent" whitewater kayaker, have done the Upper Gauley over 5,000 CFS, North fork of the Payette around 2k, fish creek in Idaho over 15k (one of the highest runs of that time in the late 90's), and some"pretty hard" steep creeks in W.V, upstate N.Y, Vermont, Colorado, Idaho and Montana (highest waterfall was 37'). Overall about 120 different "hard" rivers consider by most to be class 4 and up.
Also a river guide.
I have saved two people from death (entrapment) on the river (one guy had to be taken out by helicopter, only way).
Sort of my "credentials" so to speak.
Now,
When I worked on the river, firemen and police were always the "worst" customers.
Most fire departments have no clue what a "swiftwater resue" is, even when they "practice".
Most civilian resue divers are SEAL wantabes.
There are people who do know what they are doing pertaining to water rescues, but they are few and far.
On that same note, there are some police officers who have no clue about the operation of their firearm, and would be lucky to be able to hit the broad side of a barn if they tried to shoot at one.
This hits a nerve because I came upon a "scene" where two inexperienced kayakers drowned, and was informed by the rescue people at the scene not to intervene in a "recovery attempt" on the two bodies. To make a long story short, two firemen (who were "rescue divers") DIED while trying to recover the bodies.
You would be surprised how quick a long rope can kill in moving water.
