Peter Byrne wrote this past Monday that Svyatoslav Piskun would be dismissed very soon:
prosecutor general svyatoslav pyskun is on his way out the door, according to bob, who thinks pizza face will jettison the clown in the upcoming couple of weeks.
It happened much sooner, though: today.
According to Ukrainska Pravda (in Ukrainian), Oleg Rybachuk, head of the presidential secretariat, had this comment on Yushchenko's decision:
Svyatoslav Mykhailovych [Piskun] has been so hyper lately, he's opened so many cases... We've made sure he doesn't accidentally open a case against himself.
On a different note, Peter Byrne has just been denied a Russian entry visa.
Some background is here.
