Gun control is a legal system. Here in the United States, we who oppose it are always stating how ineffective it will be in actually preventing people who want guns from obtaining them, that rather its primary purpose is to delegitimize guns so that those who have them may be driven underground and the legal maintenance of the gun culture made difficult.
From what I have read, India has very strict "gun control", but, as predicted, it does not do that great of a job of actually keeping guns from those who are willing to violate the law to have them.
