Look out circular

Look out circular (LOC) is a circular letter used by authorities to check whether a traveling person is wanted by the police. It may be used at immigration checks at international borders (like International airports or sea ports). In India, LOC has a given proforma which have identification parameters of criminals and help police to catch absconding criminals and stopping them from crossing borders.
Definition.
The Look Out Circulars are opened to trace the absconding criminals and also to prevent and monitor effectively the entry or exit of persons who may be required by law enforcement authorities.
The basic substantive guidelines regarding the publication of the LOCs in relation to Indian citizens issued by the MHA enunciate the following four cardinal principles:
Misuses.
The person might not expect that the LOC has been issued against him and find it in the immigration at airport when going outside or coming to India as a surprise.
Court cases (Matrimonial/Family/Employment disputes) in India can take a lot of time (decades). If someone has court case going on who need to work abroad with short notice for example Software Engineers / NRI / Indian Origin people with families in India, can be dragged to compromise considering that LOC might be issued on missing of hearing date or summons.
The career of software engineers may easily be destroyed if he is stopped at airport going for an assignment for his employer.
Compensation.
Look out circular sometimes may issued without following the guidelines mentioned in the Official Memorendum in the references. The affected person may approach the Hon'ble Human right commission or higher courts and demand compensation for loss and suffering if any.
Effectiveness.
Many individuals with pending Criminal proceeding are living or working or travelling abroad. LOC is not issued in every case. So there is perception of corruption for not to issue LOC when it is obvious or issuing LOC when it is not required. The exact figure of LOC issued and not issued with the grounds and verification check of grounds is not available.
Many high profile individuals did not have LOC issued against them or managed to escape criminal investigation or proceeding by travelling abroad.
