I live here, have done for 66 yrs . We are not scared of guns or knives.
Is that because you not in an area of high knife crime or one of their target demographic? If you were a young male living in an inner city area it might be more of a concern.
It is a fact that you are less likely to be murdered by any means in the UK than in the US
I don't think people care how they are killed and it's unfair to compare the UK with the US. There are places in the UK that are far more dangerous than some places in the US. The UK does not have the same problems that the US has and vice versa.
Yes you could secure schools but should a civilised society have to do that?
Yes, they should. Shouldn't protecting kids be higher up than protecting banks, shopping malls, politicians etc...?
What would the downside of protecting them be? (other than the loss of democratic talking point)
You can't secure shops and restaurants .
No, but then they are not as likely to be filled with vulnerable small children. They may even contain other people with guns. Mass shootings frequently target gun-free zones for a reason.
