There are liberal think tanks and universities, as well as the FBI, ATF, and DOJ, that constantly study crime and guns. We do not need the government to finance more studies that do not have any real chance of making changes. Let private groups come back with recommendations, then limit studies to specific possible improvements.
There will be no black list on guns, and the no-fly list is more than just an approval or rejection. No software database is built on this scale without running a history of transactions (every request is a transaction), and there are many business intelligence programs that are utilized to generate active reports. Once of these is COGNOS, which is an IBM product, and is specifically designed to query giant databases to generate drill-down reports. Do you think that the government would only request that the database not keep history tables? Anyone approved for a purchase would be searchable in the database, and there you would have the beginnings of a simple registry list.
I assumed that you would have heard Obama's or Biden's speeches, considering how the media has published summaries of them, along with the quotes.
