Obviously you are free to take whatever you wish from my comment. I have looked it at a few more times since and I am struggling to see how I said what you suggest.
In one story, a man who asked unsuccessfully for a cigarette was punched, then kicked while on the ground, and died. That has nothing to do with anybody being murdered for a cigarette, unless you consider the person who asked for but was refused was somehow guilty of murdering himself, or that the killer was so frightened by a man accepting his refusal and waking away without a cigarette posed such an immediate threat that he had to be killed.
In the other story, somebody who was not present at the time of the incident relays hearsay information that a man might have been friends with his attacker, but said he did not know him, was then stabbed and died.
I sincerely hope that the police are able to get better evidence than that, and are able to secure a conviction. I do not believe that I have the right to kill somebody who asks me for a cigarette, or for my views on street crime, or for the time or anything else.
I have looked at a few news websites today but not seen any comment from a politician from any party to suggest that murder should be decriminalised for any reason. What I am not sure about is how restrictive our laws would have to be to prevent any possibility of crime, violent or otherwise. I hoped that could be construed from my comment, but I see now that I simply caused confusion.
For clarity, I do not defend people's right to kill others over a cigarette, although I am in rather favour of protecting our right to say no to those who ask for one. I also support the right of smokers to walk away from a refusal without being killed.
I apologise that my original comment was so confusing. If you want further explanation, please feel free to ask.
