So lets go through the list....
Loggers:  Nope, they aren't hunted.  Granted some enviro-nuts have spiked trees in an attempt to injure them, but they aren't intentionally hunted.
Commercial Fishermen:  Nope, they aren't targets either.
Aircraft Pilots:  well, maybe terrorists and skyjackers...
Roofers, Garbage men and the rest:  still not in the criteria I cited.  They experience accidents on the job, they try to mitigate the safety hazards with protective gear, but they are not targets for other humans.  They also aren't required to run toward the danger when everyone else is running away.

Those groups of occupations are subject to different hazards than Police Officers.  Trying to compare the two is like apples and rutabagas.
