Background checks keep guns sold legally out of the hands of those who are ineligible for the purchase of a legal gun. My father was killed by criminals with an illegal zip gun, made, not stolen, in Baltimore, one of the strictest gun law municipalities in the nation with one of the highest gun crime levels in the nation. Arming honest people keeps them alive and ends the criminal abuse of wannabe killers.
Very sorry to hear that. If I may ask, when and how did that happen, and did it make the news?
If you don't want to elaborate, that's OK too.
