All that is really meant by random is that the apperance of mutations isn't directed. That an organism that could make use of, say, a mutation that gives it thicker skin isn't going to have a non-random chance of getting that gene (ie, have the same chance as one not "needing" it).
If you look at the causes of mutation, as in mutagens and copying errors of the organism, then you can see that its not related to "need".
As far as this choice here, I'd have to say that its more politics than science, in all honesty.
