You expressed no concern for the girl, and your concern for her family was only to the extent of what they would think if their daughter had been killed by a murderous immigrant, specifically (presumably, you think they would feel better about it if it were a home-grown nutjob).
My point, really, was that your reason for posting had nothing to do with your care for the girl's welfare and that the theme of the thread was unrelated to that and more a jumping off point about whether or not we need to close our borders to either foreign murderers, foreign criminals, or just foreigners in general.
And that's fine - it's just jh30uk doesn't seem to be happy with that line of debate, which is why I had to clarify the purpose of the thread to him/her.
