So when someone in the UK gets stabbed, or gets splashed with acid, knives and acid are to blame? Do we just start banning all knives and acid now? It has everything to do with mental health.
Tighter gun laws in the US won't solve anything, cities like Chicago that have the strictest gun laws in the country has one of the worst rates of gun crime. Banning guns in a country that has around 300 million of them, will make law-abiding citizens easier targets for criminals and unable to protect themselves. Only way to solve it is if you can take every gun off the street overnight, which will never happen.
Think the only way of minimizing school shootings, and prevent many deaths is to allow schools to arm themselves

Chicago HAD some of the toughest laws, it no longer does. In 2008 a ban on handguns in Chicago was found unconstitutional when guess who fought that in court. A registry of gun owners was discontinued in 2013, recently a rise in gun violence was found to be 61% hand guns, something that were banned multiple years before but were now legal.
Most importantly, Chicago and Illinois are connected to.... everywhere else in america and with it easy to cross state borders gun laws in a single city aren't going to be a major measure against gun violence.
The NRA and republicans have vilified Democrats for "wanting to get rid of their guns" when the democrats literally never go after gun ownership. All they want is gun control, like stopping people who visit ISIS websites from being able to buy a gun, stopping people under psychiatric care from being able to buy guns, stopping known criminals buying guns, etc. The NRA fights these because criminals or those who wish to do harm buying guns brings them profit and profit to the gun companies is more important than american safety.
Law abiding citizens don't take their guns to school, or to street corners, and when a group of people bring a gun each to your house, your own gun is more likely to escalate a robbery into your family being murdered than it is to protect you.
But again if everyone has to register guns, if criminals can no longer buy guns then over time as criminals are found with guns, illegal guns do come off the streets. Guns come off the streets today and for decades, when criminals are arrested with them they get destroyed, but when anyone, often including themselves, can simply buy replacements it's meaningless. If you had countrywide gun control with proper registration then anytime someone makes threats against a school for instance the police can immediately go around and seize every gun that person has access to. Today that is impossible but it would be pretty easy to achieve if republicans didn't block such measures at every single turn.
Today even a criminal who couldn't get a gun legally in Chicago or Illinois can drive pretty much 30 minutes away and buy a gun in Indiana with no waiting period, no registration and no gun licence. Strict gun laws... utter nonsense. When you can drive 30 mins away and buy a gun with no delay you have no gun laws. If Indiana also required a licence, registration and a waiting period then you couldn't do that, you'd have to go to the next state that allows it. If all states did it, that guy will suddenly find it much harder to get a replacement gun.
