How is it possible for this 'terorist' to access this venue, then shoot five people, killing one and then escape totally undetected - not a single person saw this person either coming or going? Hard to believe, right? Impossible. As for the police, it's an open secret that Inidan 'police' are notoriously inept, incompetent and unprofessionally, being so ill-trained, ill-equipped and ill-led - just a bunch of greedy, corrupt, amoral thugs in ill-fitting uniforms.
