Court hears arguments on Pistorius appeal

South African prosecutors say Oscar Pistorius' sentence of five years in prison for shooting dead his girlfriend is nowhere near enough punishment.
They want the double-amputee track star to be convicted of a more serious charge and to face a longer prison term.
On Tuesday, a court in Pretoria began hearing arguments for and against an appeal of the original verdict in which Pistorius was found guilty of culpable homicide, or negligent killing, in the death of Reeva Steenkamp.
Pistorius wasn't expected to attend the hearing.
'Shockingly light'
In appeal documents filed previously, the prosecution called Pistorius' sentence "shockingly light" and inappropriate. They had originally sought conviction on a charge of murder.
Prosecutors are arguing that Judge Thokozile Masipa misinterpreted a complex South African standard defining a technical form of intent that proved to be a central aspect of the case, according to CNN Legal Analyst Kelly Phelps.
As a result, prosecutors argue, he should not have been convicted on the culpable homicide charge chosen by the judge.
In explaining her sentence, Masipa concluded that Pistorius did not intend to kill Steenkamp.
