As a police officer, you use tear gas on a violent mob after adequate warnings. As per guidelines, after dispersal which of these steps would be incorrect?

By checking options:

(1) Arrest those left behind at scene → It is necessary to arrest those who left behind and are involved in the violence.

(2) Provide medical aid if required → After dispersal if anybody want medication than medical aid should be provided.

(3) Allow media entry into the area → It is not right to allow media into that area as they make news as per there interest or benefit and may be that will create some kind of chaos.

(4) Videograph for identification → It is necessary to do official vediography so that identification can be done of those who are involved in this violence.

Hence, the correct answer is 'Option 3'.
