Look at the cluster of holes in that window. A single ragged hole would suggest near contact range. But then there is a slew of holes tapering off to the left as you look at the car. What does that say? What caliber does this look like (taking the spalling effect into consideration)? Does the cluster of holes suggest that the fire was aimed or was this a shoot from the hip scenario? If the fire was not aimed then the shooter was confident that there was no way to miss since the range was close and enough ammo could be expended to verify the result visually on the spot? He also knew he was in no danger from any sort of a security detail, so he could concentrate on the task.

Mr. Gemayel was a powerful political symbol of the Christian community in Lebanon. In the 1950's, his grandfather, also named Pierre, founded the Phalange Party, for decades the dominant Christian political group in the country; its militia eventually became a major part of the Lebanese Forces. He died in the 1980's.
Mr. Gemayel's uncle, Bashir, was a Christian militia leader who was elected president but was assassinated before he could assume office; his brother Amin, Mr. Gemayel's father, was chosen to serve as president in his place.
