Deep calming breath lickskillet... now go call law enforcement and file a report. Dont wait till it escalates because the fact is it already has. Ask for an officer to come out and have a calm chat with them. The mere fact that they are at your place is going to make the idiots.. I mean those people to think a bit differently. I am afraid it will get worse if you dont ask law enforcement to step in and calm it down now. If your the one who calls and if your the one who is calm and quietly determined to get this ended with the help of the law then you are the one who will come across as sensible and law abiding. Law enforcement is going to size up the other crew the minute they contact them about this and then you will be on record with the law as trying to get this stopped while they will come across unfavorably. Its their job to handle this let them do that for you and give you and your family peace of mind.
