You are right on about this. Same for the local shows here. 50 handguns on the table, every show and marked "private collection". These guys are the problem.
So back in the day when you mail ordered firearms without a license or FFL and we didn't have the problems we have today, please explain how "dealers", "background checks", waiting periods, and general gov. intervention have solved or diminished crimes by any of the people who shoot other people? The goal of all of those is to inconvenience the law abiding to abandon firearms and self preservation and let gov. take care of you. Do away with all of those rules and you'll see no increase in crime, and perhaps a drop due to a higher rate of firearm ownership for those on the fence about dealing with the hassle. Start incarcerating violent felons and crime would drop immensely, but the goal is to increase crime hoping you'll beg government for help. .......and here we are.
The guy with the table full of handguns is the same as a guy selling hammers IMO. Hands, fists, and feet are the primary weapons of violence.....gonna regulate those too? I travel in some of the highest crime areas of the country for work without conventional weapons. They are this way because there are influential people that want it to be so, it's not a coincidence or accident, or bad timing, it's all by design. My fees are based mostly on project risk, physical and financial.
