Awhile back I was leader of a senior citizens group at our church and we had monthly luncheons including a program of something of interest. One month we scheduled a security expert from the Albuquerque Police Dept.
Just some of the stuff he taught us:
--Women should not carry purses these days. If you MUST carry a purse carry it concealed under a jacket or shirt. Drive by thieves will snatch it from your shoulder or out of your hand in parking lots and they don't care if they drag you or kill you in the process.
I have had my billfold stolen twice--once out of my purse at the office and once out of a grocery basket. (Thieves watch for women who leave their purse in a shopping cart. If she turns her back for just a second, they have it.)
I no longer carry a purse. I carry a billfold in a snug side, not back, pocket. My phone in another pocket. And I can honestly say it has been a freeing experience and I haven't missed the purse. Of course I have to be sure to have pockets when I leave the house.
The officer said never carry more than you absolutely have to have in your billfold even then. (I haven't quite obeyed that suggestion yet.)
--Be aware of your surroundings and the people around you at all times. Anybody who looks like they are just hanging out and not shopping or doing business in a place, give a wide berth. Do not enter an area where you would be alone with such people. In parking lots where you would be vulnerable, ask for security to accompany you. Always check the perimeter of your parked car, glance under it and in the back seat before entering.
2. Hombre and I do most of our shopping other than groceries on line, do most of our banking on line, etc. and have never had a problem with that. BUT....we do business on line ONLY with reputable known businesses that have secure accounts--you can tell secure accounts by the little padlock at the beginning of their URL/on line address. Even then if you don't know the business use something like Pay Pal for on line payments. I do that even here at USMB because the staff is anonymous and always changing and I don't know who might have access to my credit card number. USMB does have a secure account though.
Also use a bank that can and does monitor charges to your account and will notify you immediately if there is anything unusual that shows up. Our bank always notifies us if we make a large purchase when traveling or there is an unusual charge on our credit card to be sure it was us who made it.
All sensible stuff really, but most of us don't even think about it until we get attacked, scammed, robbed or whatever.
