Brief sociological experiment while walking up G Street NW

When I came out of the Au Bon Pain restaurant down the street from my office, I noticed a woman whose face was horribly burned and disfigured. I decided to conduct a sociological experiment that would compare manners (specifically, the acceptability of staring at a disfigured person for longer than you'd look at anyone else) in different races.

So I walked really closely behind her as she walked down the street and watched people's faces as they passed her. My results are thus:

Black people (I don't know if they were African-American, just African, British, French, who knows, so I can't be PC) NEVER stared. The most they did was glance in passing.

White (non-Hispanic) people stared some of the time. I'd say about 25% of white people passing stared at her.

Hispanic people stared almost 100% of the time. One lady turned her head to get a longer view.

Maybe in Latin cultures it's not rude to stare and for blacks in America it's a complete no-no? I don't know. I will admit that it's really not cool to exploit unwitting people to satisfy your own curiosity (i.e. the rudest of all was for me to follow her).
