I can just picture it now. Fellow on his back in the middle of the street, not breathing. Fifty people standing around looking at one another, saying: "Sorry, can't try saving his life, I don't have a rubber glove on me."
I have seen this happen. Waiting for an Amtrak in California, an eldely gentleman just collapsed. NOBODY went forward to help him except my Mum and another gentleman, who was a British Doctor. Everyone else just averted their eyes.
Disgusting.
