How do you say "racial profiling" in German?

This is Monty:

Monty is the NCOIC in the office where I work (NCOIC = top enlisted soldier). He's been here a while now and we've become really good friends in that time. Both he and his Dutch wife Marlene are super people, easy going and fun to hang out with.

About a week ago, Monty was running in the morning before work on the Bismarckplatz near our house. It was early in the morning and there usually aren't a lot of people out around that time. At one point there was a lone German woman walking a bit ahead of him and as he was getting closer he let out a little cough. She heard the cough and turned around and as soon as she saw Monty, she immediately clutched her purse, shifted it to her other arm and adopted a terrified look. Fortunately, Monty is not one to be offended by such things. In fact he usually has a sense of humor about them, so as he passed by the woman, he got sort of close to her and let out a huge "AAAAHHHHHH!" with his arms spread out to his sides. Scared the hell out of her. Then he turned and laughed and said "I'm not going to steal your purse, don't worry!". She obviously recognized how silly she must have looked because she started laughing as he continued to run on, suddenly aware of her faux pas.

But we all got a pretty good laugh out of it in the office...
