Transfers and suspensions remain the age old police's machanism to deal with public pressure. It has solely symbolic value with temporary discomfort to the culprits.
Indian police should develop fast track 'court martial' style enquiries and action that not only punish the person heavily, but ensure they are prosecuted to the maximum by the law.
These culprits deserve severe punsihments because not only oftheir crime, but because of they trample the embodiment of trust on law. These guys on the contrary remain on suspension that is a soft punishment and reflects badly on the department's seriousness to put its house in order.
