GARDAI were on high alert as gangster David Goulding walks out of hospital today -- 48 hours after surviving an attempted hit. Armed garda patrols were increased in west Dublin this weekend after the notorious hood was released from James Connolly Memorial Hospital. Crime kingpin Goulding (32) had a miracle escape when he was blasted six times at close range as he sat in a car in Hartstown on Wednesday evening. Despite being hit six times the criminal escaped serious injury. Gardai are now probing whether Goulding was targeted by former associates in the botched hit, which has raised gangland tensions in west Dublin. Some of the criminal's henchmen are now expected to take revenge for the assassination attempt, which is linked to at least two shooting incidents last year. Sources...
