I had an air rifle at 14 , went to the next town to buy it used from a gun shop , security check was, are you 14 , yes , ok then, it was cheaper than I though so I bought a huge knife with what money I had left
came back on the bus , nobody batted an eyelid at a kid with an air gun.
I was riding to my cousins house when a copper saw me and waved me down , it was in a case so legal
He took it out, checked it wasn't loaded , asked me if I was 14 and where I was going to shoot it , happy with the answers and let me go
I'd expect armed response and a helicopter if that happened today
