Congress sit-in may finally lead to new gun laws

Growing number of politicians from both parties believe action needed to prevent more massacres.

The dramatic sit-in in the US Congress demanding action on gun control could yet deal the firearms industry the kind of body blow that crushed the country’s once all-powerful tobacco giants.

The sit-in, led by 76-year-old Democratic congressman and civil rights-era icon John Lewis, will not end gun massacres in America but it will almost certainly become a turning point in the battle.
