Sorry for the delay in getting back from you. I was away from my desk for a little while.
A restraining order is a civil matter. Basically, you tell the court you were threatened and fear these people may do you harm. The court orders them to stay away from you and your property. If they violate the order, they would go to jail.
These orders are commonly used in domestic violence issues, but they can be used among people where there is no relationship other than one posing some continuing threat to the other.
There are no guarantees that these people would obey such an order, but it does increase the consequences for them if they do. Of course, even if they had been arrested, that is no guarantee of safety either since simple assault or property damage would probably only merit probation for a first offense.
