So you consider the behaviour to be normal?

Depending on how you define "normal". If you mean acting like everyone else, then absolutely not. My goal was to be incongruous.

If you mean acting calmly and naturally, then yes. I wasn't nervous because I knew that I wasn't doing anything wrong. I wasn't doing anything that would get me in trouble.

We might fail to notice someone else stealing because our attention is elsewhere whilst with people in that demographic our attention will be much more tightly focussed; according to our records this has never happened however.

If you are watching the young males, how can you be sure? What kind of inventory shrinkage do you have?

In your opinion is it wrong for us to behave in this way?

We all have our biases. Whether or not it's wrong is debatable but if you miss a shoplifter because you were focusing your attention on the wrong person, that is your fault.
