> It is a problem, true. But suspicion never killed anybody.
A classic, recurring bug in the design of the human brain, one that gets triggered in me all the time, is that we naturally conceive of the whole world being like the tiny part that we experience; it takes serious effort to workaround that bug and walk in another person's shoes. Personally, I try to look for a specific signal: When I solve a problem - one I haven't experienced myself - by minimizing someone else's experience of it. e.g., 'That's not really a big deal.' Well, due to the bug referenced above it's not a big deal for me, but that attitude gets humanity in a lot of deep sh*t.
Thus, I'm not going to tell the GP that it's not a big deal; I don't have to live under constant suspicion every time I'm in public - though I imagine that would be awful. I do know that harassment of black people by law enforcement (and civilians), which often results from suspicion, is a very big and widespread problem. Look up 'driving while black', or 'stop and frisk'; you can read many, many stories of people being searched dozens of times, being humiliated such as being made to drop their pants on the street for a 'search', being assaulted ...
Think of it this way: Stop & frisk is a very widespread police tactic. So has it ever happened to you? Or to anyone know know? Even once? For most people reading this, the answer will indicate the bubble we live in. I'm pretty sure that if some attorney on Wall Street was stopped and frisked, or made to drop his pants, even once, the program would be over by the time he buckled them back up.
> To take it to the level of mortal danger
This isn't a realistic standard. Most serious problems in the world are not mortal danger, from assault to rape to being imprisoned, harassed, forced to eat in a different restaurant because of the color of your skin ...
