The possibility of bail exists. Barely. Usually it's " No Bail" or very high bail for a Federal charge, and he has at least 2 Federal charges against him.
I hope it's clear that he lives in a warehouse on the Duggar parents' property with his wife and 7 ( soon to be 8) children.
His parents, who are likely his only supporters, have minor daughters at home, and all of his adult siblings are married with one or more children, except a newlywed brother or two who both married this spring. ( I'm not implying they'd let him in the door).
His sentencing and disposition should occur very soon. As we know, all are presumed innocent in the US criminal justice system until proven guilty.
Sure, people try to say a stray adult *advertiser censored* image got on their HDD by accident, but we are not talking 1 or even 10 images of CSE. Many illegal images are believed to have been procured from a known source, and found on Joshua Duggar's computer or computers. Still, possession of just one image of a child being exploited sexually is a Federal crime.
After all he's done, and with this now, I'm bowing out. I can find absolutely no defense of him in my heart at all. This is NOT smoke and mirrors, it is factual hard imaging of children being exploited. Closely linked to foreign terrorist cells, who embed messages to each other and to procure new recruits in the files too. That's why HSA gets involved with the FBI now. His targets have always been the weakest of society, not fighter terrorist cells.
( I am not implying that Joshua Duggar had any interaction with a foreign terrorist cell directly or for the reason of terrorism against the USA).
I believe in innocent until proven guilty but IMO, he hurt his sisters with forceful deliberation and malice of forethought and I can't really separate his sex crimes in my mind.
IF he's found guilty, I hope he never walks free again. That's how I feel about all who exploit vulnerable men, and all women and children through criminal sex acts.
