People are still confused and distracted by the pension thing. Police officers, like everyone else keep their pensions if they are dismissed. Guildford had already retired once, it is therefore reasonably likely he was no longer paying into a pension scheme any more, so there is no protecting a pension.
The only circumstances a pension can be taken is after a criminal conviction in connection with service. A small number of pension forfeitures take place nationally annually,Wayne cousins is the most well known one.
If Guildford was motivated by money he would have waited to be suspended either on s38 or through the misconduct route. This would have kept the situation rumbling for years at a significant cost to the taxpayer.
