misguiding perception (real life)

this is exactly the type of everyday real life situations that the suspect backpack project hopes to address, see:
http://gizmonaut.net/bits/suspect.html

If i'm short, slightly dark-skinned and wearing a backpack...

...do i get considered as the "other"? As someone to be suspicious of?

just because i meet all the right criteria: slightly darker-skinned [tick], in a hurry [tick], mobile phone [tick], jacket [tick], backpack [tick]
Doesn't this describe a significant proportion of the people in the world?
