Wrong way to judge

It is unfair and useless for a police bureau to punish undisciplined policemen according to a certain percentage set in advance, says an article in Beijing News. The following is an excerpt:

The police bureau of Changchun, Jilin province, is determined to take measures to improve the discipline of the police force. It is a good thing, but one of the measures has attracted public concern.

Only 1 percent of the entire police force will at year's end be picked up as examples of poor discipline and sacked if they cannot improve themselves. Why 1 percent and not 2 or 0.1 percent? The bureau has not explained. This definitive figure concerns real people who are likely to lose their jobs.
