I feel for you.
You must have your gun ready ALWAYS. And also go to target practice regularly. Do not forget, it may save your life! Take it seriously.
Not only this. Make sure your phone and cell phone are close to you. Put bars on your windows and alarm. Get a large dog. Apply sings "protected by dog" and "protected by alarm" everywhere.
You can not rely on the police.
Don't forget, in the US SUB-humans have rights, not people.
Good luck.
