I am not sure why it is such a HUGE deal when someone is injured or, God forbid, dies doing something that's pretty risky in the first place. Of course it's truly a shame when someone loses his life in the process of doing his job. However, there are some jobs out there that are pretty damn risky.
When a reporter walks into a battle, there's a high probability he'll get blown up or something. When a miner lowers himself 2 miles deep into the earth, there's a pretty good chance of a cave-in. Construction workers on a tall building? - you might slip and fall. Fireman? - you might burn. Policeman? - you might get shot. Zookeeper? - you might get attacked. Sharpen kinves? - you might get cut. There are risks taken with these jobs. So why is it a big surprise if someone dies or is injured in the line of duty?
It's the postal workers who get shot at work that is unexpected and newsworthy; the baker who gets stabbed, the financial analyst who gets poisoned, the office workers who have a plane fly into their building. The death, or even injury, of these people while at work is news - hard news to concern yourself over. (But if a hooker gets beaten to death, most people think, "Well she was asking for it, putting herself in that situation.")
Unions and safety measures, no matter how strictly enforced, will never be able to remove all the risks of some of the most dangerous occupations. You can't have a battle without weapons. You can't study sharks without getting in the water with them. You can't have clean windows on the 35th floor without washing them. Truly, you (subjective) have no one to blame but yourself if something happens to you while you are doing something dangerous. You put yourself in an unsafe situation. Making a big deal about it won't make it any safer of a situation. Only so much can be done. The rest is a crap shoot.
