"Two teenagers have been arrested on suspicion of attempted murder after a man was stabbed in Bristol. The 20-year-old victim was walking along Bishopsworth Road with two other men when they were attacked by a gang. He was stabbed several times suffering a punctured lung but is said to be "stable" at Bristol Royal Infirmary. " (http://news.bbc.co.uk/2/hi/uk_news/england/bristol/somerset/6985782.stm)
Removing guns from the equation doesn't put an end to violence and murder, so please, don't focus on reducing gun ownership, focus on reducing violence.
