I think a lot of people just don't want to get involved.

But, on the flip side, I did read something today that renewed my hope in helping one another:

I saw letters of commendation for 2 civilians who went above and beyond anyone's expectations in helping a motorist who had a cardiac arrest and crashed into a pole. The crash exposed live wires, but these 2 individuals did compressions and the other guy even had his own defibrillator (he's apparently a life guard/ski patrol). If nothing was done until help arrived, the motorist would most likely have died.
