The national guard do not carry those weapons for show, they work. Lethal force is authorized against looting and rioting.
Hopefully it won't come to that.
How do you keep looters out of your backyard? Hang one in your front yard.
Many years ago a middle-east family leased a building near my home and opened up a store. I went there a lot as I support small business. One day as I was walking in, the police were talking with the young store clerk. After they left I asked the clerk what the problem was. Apparently a drunk came in and stole some cigarettes off the counter. His complaint was that the police told him if the guy came back, give them a call and they will throw him out of the store. That's all they would do.
A few weeks earlier his grandmother wrote and wanted to know about his environment in this new country of his. Instead of writing a long letter back, he sent her a copy of our suburban paper. She wrote back with great concern because she read the police section. Her claim was we had more theft in our little suburb in one week than the entire middle-east has in a year. I asked him if that was true, and he concurred.
Where he was from they had outdoor markets with picnic tables setup for the customers. He said if a woman lay her purse on the table and walked away, it would most likely still be there the next day. In fact people who seen the purse would cross the street to be nowhere near it.
He said if somebody was caught stealing, off comes one hand, and not in a hospital either. Steal again, and off comes the other hand. He said there is no third time. That's why we have so much theft here and virtually none over there. A strong enough deterrent works every time it's tried.
