two theories:
1) it's unrelated. the chance of two things being unrelated---one worth golating about, like the favorable move by the prosecutor, one worth dreading, like pissing hot or divorce or PO troubles or whatever people are theorizing---happening at the same time are i think pretty low.
2) the motion is only a partial win for rekieta. he asked for a mile from the prosecutor and only got an inch. whatever the prosecutor says in that motion is ALL he has on his side to fight against its release (or sue after the fact). so he could be pissed because he asked for an ironclad solution but the prosecutor's amendment is only a half measure that might not work.
