Lol this is such a stupid problem for your country to have. In the late 90s after having a school shooting here laws were introduced and people had to trade in their guns and were reimbursed. Since then we have had 3 mass shootings, all of which only had a few deaths each, with a murder rate of 9 per million per year. (About 5 times less than the USA based on a quick search.)
I have a friend from Texas and I found it quite funny that he seemed to feel bad for me that everyone here isn’t armed. He’s a good guy but he seems legitimately unaware that the laws on guns are never discussed because everybody of all political persuasions is happy with them, and see the situation in the US as an extremely easily remedied sick joke.
