Now that you've vented maybe you'd answer the very straight forward question I asked twice already. I'll make it even more concise for you in case you couldn't see it properly through your red mist.
Had she gone down for murdering her 3 children would she be "eligible to apply for temporary release" after just 18 months?
There's no red mist at all. It's just an idiotic question. Anyone in prison can apply for temporary release, including someone convicted for murder. So yes, yes she could.
