Double standard of law enforcers denies fairness for migrant workers

NINE MIGRANT WORKERS were were detained by police for trying to jump off a high building in Hefei, capital of East China's Anhui province, because they hadn't received their wages. The migrant workers are victims of social injustice and detaining them won't help solve the matter, says a comment on Southern Metropolis Daily:

The local police have reasons to justify their decision. Those trying to jump off the high building posed a threat to their own and other people's safety; it was reasonable to stop them.

But where were these law enforcers when the workers failed to get their pay?
