10. remembered

Guardian Angels are people who travel on the New York subways and protect other passengers from criminals ( 罪 犯 ). They are volunteers: they don’t get paid anything to do this job. The Guardian Angels would never have appeared without a young man named Curtis Sliwa.
Forty-three years ago, if you’d wanted to travel home late at night on the New York subway, you wouldn’t have felt very safe. Luckily, on February 13, 1979, at 3:00 a. m. , the first safety patrol (巡逻)—called The Team— went into action. Curtis Sliwa and his friend Don Chin began to cleanup crime on one of New York’s toughest
subway lines, the Number 4 train. However, this was not a job for two, but a job for 13, so thirteen brave people walked into the last car of the Number 4 subway line in New York City—the “Mugger’s Express”. If they saw a danger of violence (暴力), they stopped it, using non-violent means. The group became known as the “Magnificent 13”.
The Magnificent 13 soon went from thirteen members to hundreds and they changed their name to the Guardian Angels Safety Patrol (GASP). At first, GASP faced opposition from the police, but they had the strong support of the public. Today, the Guardian Angels can be found all over the US. If you travel by subway, you will see them wearing red hats and white T-shirts. Although Guardian Angels are not armed, if they’re present, a criminal will think twice before committing a crime.
The Guardian Angels also train young people to join them in their fight against crime. They believe that if they train groups of volunteers to patrol dangerous areas in New York, the city will be safer for everybody. “If we had more volunteers, we would be able to reduce the problems many cities face: violence, crime, and drugs. ”
They have also started after-school training programs inside high schools and community centers. If young people visit the Guardian Angels Headquarters (总部), volunteers will talk to them about their work and will then guide them through the Times Square area. It’s fun. It’s safe and meaningful!
