If you don't have a personal alarm, consider such a purchase. Not only can the personal alarm foil a potential purse snatching, the alarm can also deter a personal attack. Although the logical place to attach the alarm to the purse is on the purse strap, I recommend placing the alarm inside the purse. If a theft is attempted, the alarm may not sound as loud, however it will be more difficult for the purse snatcher to remove the alarm. Consequently, there will be a better chance to thwart the purse snatching.
Most men place their wallets in their back pockets an easy target for any pickpocket.
Some 20 years ago, when I traveled overseas to visit an unfamiliar country, I decided to put my wallet in my front pocket. I believed that it would be more difficult for a pickpocket to reach into a front pocket to pick my wallet. I've continued that practice ever since. Better yet, if you are wearing a jacket with an inside pocket, use this inside pocket to hold your wallet. One final suggestion is to Velcro your wallet pocket.
