Try not to shop alone, take a buddy with you. If you are shopping alone be aware of others and your surroundings. Do not park your vehicle in an unlit, unpopulated area. Do not carry an over abundance of packages. Once you purchase items take your packages to your vehicle to free your arms.
Most malls provide security inside and out.
Women, Try not to carry a large purse. If you carry a purse. Do not carry it loosely on your shoulders. Keep it in front of you with a firm grip. Know at all times where they are when shopping.
