Sky News has reported that "one of the first police officers on the scene of the Haymarket car bomb may have saved dozens of lives by defusing the explosives before the bomb squad arrived. It is believed the quick-thinking cop recognised that the car was wired to blow up, jumped in and disconnected the trigger device, thought to be a mobile phone."
Quick-thinking and courageous. In fact, if the report is true, the type of officer who does not think about himself but only of his (or her) duty.
What a difference there is between a person such as this and the thankfully incompetent persons who left cars loaded with "petrol, a large amount of nails and several gas canisters".
