Were my daughter's friends civil rights violated?

My daughter's friends were waiting for her in our private townhouse lot, which has visitor parking, in their car with the lights out. A neighbor put a flashlight in their car and asked who they were. They said they were waiting for my daughter. The neighbor said they couldn't wait in the car and made them get out to go to our house. My daughter was visiting and I was babysitting at my house. My daughter and her friends are 25 years old. An altercation insued with my daughter and the neighbor about making them get out of their car. I can understand the neighbor questioning strangers in a dark car, but asking them to leave and not sit and wait for my daughter does not sound like it is any of her business.
