Because "gun control" is not about reducing crime against individuals; it is necessary for taking away the final freedoms of individuals. It is People Control, purely political.
Not in the UK, where most people are disarmed.
But in the USA, where there are 2,500,000 reported cases a year of citizens using a firearm to stop a crime, widespread gun ownership by honest citizens demonstrably reduces crime.
This Monday, just a few miles from my office, a woman coming home from work late at night was attacked in her front yard by a man with no identification, who strangled her a bit, before she drew her .40 S&W and killed him.
The whole discussion about whether someone "can justify" owning a vehicle capable of going faster than X mph, or a truck "larger than they need", has no place in a free society. It is nobody's business except the person who wants to buy the car or truck... or airplane... or boat... or gun. This is all socialist clap trap, from arrogant little tyrants who want to tell other people how to live, as if they know best. Call the nonsense out and shame them early or, like all bullies, they become bolder.
