My opinion to gun control is to help the securty of one country. only the the low enforcement have right to hold gun unless you have a good reason to have gun or buy gun for protection. not only like toy you buy and no need document.
How are these documents to be stored and used?
Do you suppose that at the local level there might be only a few degrees of seperation between some worker in county courthouse and a set of local meth-heads, and that information about who has guns and who does not might make it out and around? I can pretty much promise that that would be the case where I live.
Or should the information be considered 'high security' and only available to those at the highest levels of government? If so, for what reason might the information be used? In what circumstances would the information be useful, and to whom?
Perhaps it should be shared with large social media organizations (Twitter, Google, Facebook, Amazon, etc) and the task of coorelating risky individuals should be outsourced to those who already have other data on individuals (known in the industry as 'PII')? Or perhaps the government should be able to tap into the data collected by these large multi-national corporations in order to run the algorithms? Which way would you like to see it go?
