It's only a violation if he didn't contact his probation officer about this, and no one has proven that he hasn't contacted his probation officer about this.
Except the onus is on him to prove he has in fact contacted his PO and he has in fact obtained (written) permission. Not on "anybody" to show that he "hasn't". Seriously, logic. Let's all use it.
Why does he have to prove anything to anybody? You're the one making the claim that he hasn't contacted his parole officer, or has otherwise somehow violated his parole, when you have zero proof that he has done so. Why should I believe your claim when you fail to provide proof? And why do you think it is on him to prove to everyone that he has contacted his parole officer? Your logic isn't making much sense. Last I checked, it was innocent until proven guilty, but you're demanding the opposite.
