From the article:
"Argument is the number 1 motive this year... A third of homicides, 30... Started with an argument... One over five dollars... Another between two brothers arguing who was the better parent."
So, avoid arguing with anyone.
"The second most common motive is robbery. 18 homicides this year began with a robbery. Up 25 percent from last year. Scott says more people are resisting."
If you get robbed, just give up your valuables.
"Chances are you'll know your killer... 71 percent this year have."
Assuming you don't know anyone in Memphis, the odds are on your side.
I'm not trying to make light of murder. But, there's really no reason to avoid any city in the United States in fear of getting killed. Just use common sense, as you should whenever you're in an unfamiliar area.
