Mochache said Saggar had communicated with the women five
days to the attack.
The court said the officers were acting in self defense after
the women hurled a petrol bomb and stabbed police officer
manning the station.
The court has a duty to safeguard the lives of people
including State officers.
"If police officers did not act in speed, there could have
been more deaths at the station," Mochache ruled.
The court however found her not guilty of being involved in
the planning of the attack saying that the prosecution did not
prove its claims.
Detectives claim Saggar communicated with Tasnim prior to the
attack and there was some financial transaction between them.
The troubled widow has been in court several times, defending
her late husband Rogo over terrorism charges in court.
Rogo is believed to have had close links to Fazul Mohammed,
the leader of Al Qaida in East Africa, whom a US court indicted
in 2008 for the 1998 US embassy attacks in Kenya and Tanzania.
