Is there any laws broken when someone is following you in their car?

my girlfriend was followed last night and i was wondering if there were any laws broken, by someone doing this.
Even if there was no laws broken the police would probably have a chat with him and ask him what he was at.
NO...unless there is a restraining order on them (100-1000 feet away)
Free Country.


Answers:
There are laws covering harassment, but it would require a pattern of harassment being established, not just one incident. Check with your local police department, or with a lawyer.
