CMV The 2nd Amendment is necessary to the safety of all citizens

My view is that the 2nd Amendment is not just defence against a tyrannical government, but defence from people who want to harm you or your family. I've had multiple family friends have break ins and they all say that their gun was the only thing that stopped the robber.

"But what about Britain? Their gun violence went down!"

And knife violence SKYROCKETED shortly after their ban. As well as daytime crime, and "hot burglaries" (Burglary when the home owner is home). As well as the recent acid attacks and grooming gangs that terrorize the country.

"Cant have a bad guy with a gun if they're outlawed!"

Reducing supply without reducing demand causes a spike in sales from alternate sources, e.g Cartels. You'll be taking guns away from properly trained people who have genuine reason to arm themselves.

"A ban on guns is a ban on gang violence!"

Again. Supply and demand. That is, assuming they didnt already acquire their firearms illegally. Studies show that only 3%-10% of all murders are committed with a legally owned gun, and a large percent of uses of a firearm are to STOP an ongoing crime (No exact % due to wildly fluctuating estimations between Bureaus)

While these are true, aren't their overall crime rates comparable or much lower than ours, in general? And looking beyond just Britain, for the most part every other major developed country has gun bans, and some of them *definitely* have lower crime than we do.

>As well as the recent acid attacks and grooming gangs that terrorize the country.

It seems very unlikely that banning guns is going to cause a strong spike in crime 20 years later. Why the lag?

>Again. Supply and demand. 

Why don't countries that have gun bans see this already?

As you said yourself- gun violence in Britain *went down*. If it were the simple supply/demand picture you're painting, why did it have such a strong effect there?

edit:

From your link in the comment:

"The policing minister, Nick Hurd, said that crime, as measured by the crime survey, was down by a third since 2010 and by 69% since its 1995 peak."

(as another commentor mentioned, the UK's ban went into place in 1996. So overall crime is still way down after the ban. (with the caveat that most countries have seen overall trends of declining time over time in the past few decades, with some fluctuations)
