OPINION - The Standard View: The action needed now to end the bloodshed in London

As the weather turns warm, a grimly predictable violence is rearing its head. In the last few days, two young men have had their lives cruelly stolen. Rene Graham, just 15 years of age, was shot dead on Sunday in a west London park packed with families. And yesterday, another 15-year-old was stabbed to death on a visit to his former primary school in Hackney.
