Robert recently attended a lecture on safety at a neighborhood center. The speaker was Detective Garcia of the New York Police Department. Here is what he said:
    The first thing you need to do is to get to know your neighbors. Don’t be shy. Introduce yourself, especially to people who live in your building. We people who live in large cities often are reluctant to make friends, but it may save our lives later.  So make sure that you know your neighbors and that they know you.
    Second, don’t carry a lot of money with you. If you’re a man, put your wallet in your front pocket; it’s harder for a pickpocket to lift it out without your knowing. Women, get a purse with straps that you can slip over your shoulder and under your arm. Don’t carry a small purse that a robber can grab from you easily.
    Third, if you are mugged, don’t resist. I wish people would listen to me when I say that. A month ago a fifty-year-old man ended up in a hospital because he thought he could beat a mugger in a fight. But if he hadn’t tried to be a hero, that probably wouldn’t have happened. Don’t try to be a karate expert. Give the mugger what be wants. As soon as he leaves, call the police. Report any lost credit cards without delay.
    Finally, remember that there’s safety in numbers. Try to avoid dark, deserted streets at night. Also, do not get on empty subway cars. If you’re traveling at night, get on the car with the conductor.
