SpaceX Plan To Fuel Rockets With People Aboard Raises Alarm Bells (fortune.com)
Several space industry experts that advise NASA have told the US space agency there are safety risks in a proposal by Elon Musk's SpaceX to fuel its rockets while astronauts are on board. From a report on Fortune: "This is a hazardous operation," Space Station Advisory Committee Chairman Thomas Stafford, a former NASA astronaut and retired Air Force general, said during a conference call on Monday. Stafford said the group's concerns were heightened after an explosion of an unmanned SpaceX rocket while it was being fueled on Sept. 1. The causes of that explosion are still under investigation. Members of the eight-member group, which includes veterans of NASA's Gemini, Apollo and space shuttle programs noted that all previous rockets that have flown people into space were fueled before astronauts got to the launch pad. "It was unanimous ... Everybody there, and particularly the people who had experience over the years, said nobody is ever near the pad when they fuel a booster," Stafford said, referring to an earlier briefing the group had about SpaceX's proposed fueling procedure.
This is the kind of question that was asked after the Apollo 1 fire. Yes, there are risks in spaceflight. That doesn't mean that there isn't way to mitigate risks, or that undue risk has to be taken.
I imagine the benefit to fueling with the people already in the capsule is that you'll have less liquid oxygen boil off before launch, if you can launch as soon as the thing is fueled. Is that worth risking the lives of people? No, especially as you can likely fix it with a procedural change.

These systems have been around forever, SpaceX is (once again) doing nothing new or special. They only work when there is forewarning, and that is unlikely to be had during a fueling mishap. This isn't a cartoon or action movie, you can't just outrun an explosion in progress by jumping fast and wearing cool shades.
