Dear Mr. Dinesh Divekar, I have studied these matters in depth. It is up to you whether you accept something speculative or act on rational data. Yes, it is quite possible, as you say, that the person may be engaged in terrorist activities. But what are the likely indicators, facts, data?
Blindly acting like a policeman or bureaucrat is not going to be helpful. You might recall that when it came to light that some terrorists used pressure cookers/tiffin boxes and bicycles for planting bombs, the police issued an order that henceforth anyone buying these items will have to furnish KYC documents like ID, photographs, etc. Now, don't you think that this causes unnecessary harassment to the general public?
And for your argument that the person may have joined ISIS and come back, do you have any data? How many persons have done this? Moreover, a skillful HR can easily find such things during the interview itself. I think that is the purpose of having a personal interview, to ascertain suitability. Just for such a figment of imagination, if you want to harass millions of job-seekers, you are most welcome!
I can only say that I am lucky that I never sought any job in your organization. Yes, you can ask for millions of documents, and yet I can assure you that in no case can you prevent any untoward incidence that may occur. If taking affidavits would have been such a potent remedy for everything and every offense, there would be no need for police, judicial systems, law enforcement, or anything. This world would become a Ram-Rajya!
So, my friend, you are entitled to your opinion (just as I am to mine), and I wish you all the best in your endeavor. Just to add, I write long messages where it warrants. This query demanded a long detailed reply.
Here is an issue of only a four-month gap. A person is fully entitled to have a break of four months without assigning any reason or explaining under oath—that is what an affidavit is, one has to state something under oath. As a matter of fact, these days, whoever is aware of the job market will agree that a four-month lead time is not sufficient for completing the process of getting and joining a new job.
As already pointed out by me, if an HR thinks that the person has been jailed during this time or, as you mention, that he has been into ISIS training, then anything can be assumed. I have even seen some more bureaucratic HR who even ask for indemnity bonds. Going by your assertion, I think you might also root for it.
It is easy to look down while thinking of criminality in an organization, but most often, one finds it advisable to look upwards, as one finds not just small incidences, but wrongs being committed on massive, gigantic scales.
