Not relevant to this conversation but many years ago I used to go to international Crossbow competitions. The first year I put my crossbow into a gun case for travelling. I got stopped going out at Heathrow but the customs guys didn’t really appreciate what they were looking at and were fine. One of them though was more concerned with a tube of fletching cement! I also got stopped by customs going into Portugal that year. After that I used to take my crossbow apart, wrap the parts in cloth bags and transport it in my suitcase with my clothes. I never got stopped after that. I suspect I wouldn’t get away with that these days though.
Oh, I forgot to add that I did tell customs that I had a crossbow in my suitcase once and the guy actually said to me “I don’t care what’s in there!”
People who kill animals for their own entertainment should be avoided at all costs, both physically and socially, by any means. They will drag you down to their own level, and that is not a place any decent human being would want to be.
