What should people do when the police can't be there to protect them?: With grand jury decision due soon in Ferguson, gun sales surge

From CNN:

Lately, Dan McMullen has been bringing an extra gun to his office in Ferguson, Missouri. 

McMullen runs Solo Insurance on West Florissant close to where looting and vandalism briefly broke out in early August after a police officer shot to death teenager Michael Brown. 

"I bring an extra gun now only because it has a bigger magazine," McMullen says. He began carrying it after tensions increased in the area following the shooting. He says he would never use it to protect his business, but he would use it to save his life. 

"So maybe I get trapped here or something and have to have a John Wayne shootout," McMullen says before interrupting himself, smiling. "That's the silly part about it: Is that going to happen? Not a chance. But I guess, could it? I'm the only white person here." 

McMullen is particularly cautious now, as all of Ferguson and much of the nation waits to see whether a grand jury will indict Officer Darren Wilson for the shooting. Though the grand jury has until January to issue its ruling, the prosecutor's office has said a decision could come in mid-November. . . .
