Sorry, but that's ridiculous, and I can explain why. With the barest amount of practice, a person could fire a hundred rounds in rapid succession with a pistol or rifle that holds a mere 5- or 6-round magazine. All they have to do is empty a mag, hit the release, pop in another mag, and resume firing. It can be done in less than 5 seconds. So all this stuff about a gun being an "assault gun" is really based on media hype. They started with firearms that look army-ish, added firearms that have higher-capacity mags, and now have gotten to where just about any gun-related incident they report on is characterized as an "assault gun" incident.
Let's remember that when the First Amendment was ratified, the people had personal recollection of defending themselves against an army from across the ocean. That remains a legitimate concern today. Foreign governments should always have a reason to "think twice" before giving the USA grief on our home soil. It is a deterrent.
We also have an individual right to self-defense in case of home invasions, robberies, and other criminal activities that might endanger us. The police can't be everywhere and their response times are not always what one might wish for; the first line of defense, and the obligation to be equipped for self defense, lies with the individual. You may think that 10, 15, or 30 rounds is ridiculously unnecessary; tell that to the police and you'll be laughed at! The cops know how hard it is to hit a target while under stress, and they train constantly. We citizens are likely to be far worse under the strain of a man coming at us with a hammer
or a knife or pointing a gun at us, so why have "maybe barely enough but maybe not" when we can have "more than enough" instead? (I mean, does anyone
really need more than one ebike?)
Strange, isn't it, how California has some of the most restrictive gun laws in the country, yet had 4 shootings in 1 week? So how are all those laws working for you? And you think the rest of the country should follow California's example with more anti-gun laws?
