There will always be bad people. Blaming bad people is not a useful solution to anything. And asking bad people to behave better never works!I'm sorry - but this still sounds like blaming the victims instead of blaming the culprits
The question is who is in a position to stop them. Does UP want the thefts to stop, or do they not really care? Seems like by firing all their own cops, they said "we don't care".
To put it another way -- to paraphrase an old comedy routine, "The Great Train Robbery" -- the question is who is responsible. And thieves are totally irresponsible!
