I'm somewhat on the fence about gun control. On the one hand, it makes mass shootings less likely, but on the other hand, if someone wants to go kill a load of people, there are a multitude of different weapons they can use.
Even when gun control was looser in the UK, Hungerford was the first recorded massacre, and it happened in 1987. We've been using guns for centuries before then. Gun crime may be down, but it still happens. I've seen plenty of news reports about people who have been shot in gang wars, as well as those who were stabbed. If someone wants a handgun, they will get it.
It also screws things up for our olympic shooting team, who have to go to Switzerland 6 weeks a year so they can train. I believe the handgun restriction is going to be lifted for the shooting teams, though it would be interesting watching them walk through customs.
"I'm an olympic shooter, honest!" as 20 armed coppers prepare to shoot him if he does so much as move.
