The NICS, which is the database used to perform background checks, is woefully inaccurate when it comes to convicted druggies and metally ill folks. Despite many laws requiring submittal of the names, fewer than 1% of those required have been tendered to NICS. So the act of checking NICS becomes a joke. Straw purchases and application fraud are not uncommon; they should be punished stringently. But they are generally ignored or slap the wrist of the violators. The system as apparatchiks choose to run it is a dirty joke.
The hoplophobes despise the tools of liberty in the hands of everyday citizens. We, the People, are a powerful bulwark against their egos and desired tyrannies.
