Let me start by saying that I respect the decision of Americans to value the right to bear arms over the lives of children, the deaths of whom are an acceptable price for guns being available. I just do not understand it.
Another school shooting has taken place in the USA. I am sure that there will be people who will blame this on issues of mental health, or transgenderism, rather than the issue of having decent gun controls. Living in the UK, we have legal firearms here. My job includes among other things, providing information on licences to the police who are responsible for the decision to issue them and I have no issues with legal firearms being used for hunting and also for sport.
In the UK, in 1996, following a mass shooting killing primary school children and their teacher, a ban on handguns was imposed. Years before this, following a mass shooting in 1987, semi-automatic weapons had been banned. Since then, we have had incidents where the murder of more than one person has occurred, but these have been relatively rare, one example being, how Derrick Bird killed many innocent people, followed by the murderous rampage of Raoul Moat. But this was in 2010 and while mass murder has occurred since then on several occasions our most recent high profile case being in August 2021, we have lower rates of mass shootings than the USA. Gun crime exists here, but the rates are far lower than in nations like the USA, just like how the overall murder rate in the USA is higher than in other developed nations.
