You may need a broader definition of "desperate." You're treating it as if it can only be transitory, momentary while discounting the possibliity that desperation can be ongoing and continuous.
As usual Mike K. simply chooses a convenient definition that supports his pre-determined conclusion and runs with his straw man argument.
Don't let the door hit you on your way out. Anyone who defends gun-toting robbers as merely "desperate" is not worthy of the time it takes me to recoil from their posts.
See, when you argue straw men fallacy you can say really dumb things. Things like describing someone as "deserate" is somehow defending their actions.
It is really hard to solve a problem if we are not allowed to actually discuss all the factors involved. IMO if we could alleviate the conditions that make people desperate then we would reduce crime far more effectively and economically than hiring more cops and sending more people to jail.
