Do you often seek legal advice, electrical problem solutions or marriage counseling on line from folks you do not know?
Thought not.
Go to a qualified self protection in /outside the home (NRA.org), pay for a course of instruction, get a proper firearm(s) and commence to train, practice and improve your skills, knowledge and ability to defend you and yours.
The best advice you’re likely to receive on any forum.

Not asking for personal gun use information. I am just trying to understand what store owners are facing when their businesses are threatened by rioters. What rights do they have?
