I want to expand on this because it goes back to the point I made in my first post on this thread, answering why GZ ever left his vehicle.
You really have to understand the "gated community mentality" to get it. On a public street everyone has a right to be there. I can get on a plane, fly to any city, get in a rent a car, drive around, park, and walk down any street, and really nobody has any reason to suspect me.
But if I drive into a private gated community, it all changes. Completely. People expect to know others. If they don't recognize you, they look at how you look, what you're driving, what your'e wearing, to determine if you belong. And if they can't tell, they might confront you, or call security, just to make sure. This is practically unheard of in a public street context.
So I think that's why people have such a hard time understanding GZ's attitude and behavior. Why did he get out of the car? Why did he follow TM? The answer is: gated community mentality. Perfectly normal and legal.
