Every now and then I'll be shopping and the security device by the door will beep as I'm walking out, even though I haven't stolen anything. I always just assume there's been a mistake, e.g. the cashier forgot to deactivate my security tag, and walk straight on out; I'm not going to waste my time being searched when I know I haven't done anything wrong.

This doesn't happen very often but as far as I can remember I've never been challenged when I do it.

But what I find really interesting is: based on what I've written above, isn't it trivially easy to guess my skin color?

Most stores have explicit policies not to chase people even when they visually observed shoplifting. It creates too many problems — it’s easier and safer to just turn the video over to the police.

Those security devices are generally there to scare potential thieves not actually detain or prevent them from leaving, so your anecdote doesn’t actually show anything interesting.

Nope. Maybe it would be if I the reader were in a country where people are stopped exiting a store based on race, but thankfully the vast majority of the world isn't like that.
