It's the UK, where the common people are "subjects" instead of citizens.
Whoops! Well it goes on here as well in the US.. For example, I drive a taxi here in NYC...If I am found with a gun on my possesion, whether or not I am driving a taxi, I face one year in jail and my taxi license gets immediately revoked. If I have a license for the gun (which is almost impossible to get) and I am found with that licensed gun on my possesion while driving a taxi, my license still gets immediately revoked.
But the guy who a few years ago put a knife to my neck (cutting it by the way) and took $230 dollars of my money, is still to this day roaming around and in 3 years who knows how many else he has robbed or stabbed. Last year we had one taxi driver who had a knife plunged into his spine, and another who had his throat slashed (and he died). Was it the same guy who robbed me? Who knows, but a nice piece of lead in his brain would have eliminated that particular guy from that possibility. Oh yes, last year I also had a guy point at my head a bag around his fist. Was it a gun he had? Who knows.. I immediately jumped out of the taxi and he took off, but once again I was unable to defend myself. What if he did have a gun and when I jumped out he decided to put some holes into me? All I could do was hide behind a bus.
