The only way nodding or glancing at your attacker will scare them off is if they think you might have a gun. Otherwise, you might as well start running:
DAILY CALLER – In lieu of guns, people who find themselves in dangerous situations at or near the University of Arkansas should defend themselves by glancing and nodding, said a university safety expert.
Earlier this year, the Arkansas legislature approved a concealed carry law, but gave school administrators permission to override the law and ban guns on campuses. Most Arkansas universities, including the University of Arkansas and Arkansas State University, opted to prohibit concealed carry, according to The College Fix.
But disarmed faculty and staff members are vulnerable to attack when traveling to and from campus, according to a chain of emails sent between UA staff members, one of whom was assaulted by three teenagers on his way to class. […]
Sharon Houlette, a detective with the UA Department of Public Safety, responded to the thread with advice for avoiding being attacked, which included a suggestion to “glance or nod” at possible attackers.
“A glance or a nod will help you show anyone who might think that you are not paying attention, and you are aware of their presence,” she wrote.
