In the midst of chaos the death is one bullet away!!!!

US citizen Rigoberto Alpizar, 44 was shot dead by the air marshals on board of the American Airlines flight. He satrted acting suspiciously and commented of carrying a bomb in his luggage. It was later confirmed that he didnt have a bomb in his luggages and probably was suffering from the mental illness.

According to the sources Alpizar had arrived in Miami, Florida, from Ecuador and was boarding a flight to Orlando at about 1410 local time (1910 GMT). Accounts from inside the plane suggest that Alpizar began behaving erratically before he was challenged by the marshals.
"He didn't look stable," fellow passenger John McAlhany told the Miami Herald.
As he ran down the aisle of the plane, a woman assumed to be his wife shouted for him to stop.

Its really crucial for any authority to check again and again before they open fire on the people. Of course other side of the coin holds equal stake considering that if the person did really carry a bomb then it would have resulted in higher numbers of casulties. However, its more easier to shoot a person when carrying a gun but impossible to bring back even on innocent life which has been lost in the midst of chaos!!!!
