Why are there always helicopters flying over the roof of Beijing Anhuili Community these days?

The reporter learned from the Police Aviation Corps of the Municipal Public Security Bureau that five police helicopters of the Police Aviation Corps conduct aerial surveillance on urban areas, suburbs, surrounding checkpoints and important roads every morning and evening during peak hours. In case of emergency, the police helicopter can quickly carry out aerial survey and emergency take-off and landing at the corresponding position, and provide air support for ground disposal operations according to the ground conditions, including police transportation, video transmission, air call, light search, personnel rescue and other means.

The above is a report on May 23rd, 20 14.
