Film Challenges Knife Culture
One Knife. Many Victims.
A film featuring teenagers from Glasgow has been made to warn about the consequences of carrying knives.
The five-minute movie's been released by the No Knives Better Lives campaign, and will be shown in schools and at community events around the country.
It tells the story of Mark, who's feeling nervous about bumping into another teenager, and picks up a kitchen knife before heading out with his friends.
Later, a situation at the park gets out of hand, and he stabs the other boy.
The film goes on to show the impact it has on Mark's family.
Director Martin Smith says research with youngsters before filming began revealed they hadn't thought about the wider consequences of knife crime and the stigma experienced by parents and other relatives.
He hopes the movie will make them think - and change behaviour.
That's echoed by Justice Secretary Michael Matheson, who says he wants to change the "cultural attitude" of young men in particular.
The film will be available across Scotland but screenings will be targetted at areas which have particularly serious problems.
Opposition parties have criticised the government.
It happened in Rutherglen on Tuesday.
Officers in Dumfries have taken to social media urging the owner to "pop in, tell us what's inside" and claim it.
