The problem with this case and a lot of cases – that there are two sides. He also had a Bais Din that sided with him. The reason a lot of people withold the Get is because they feel that they weren’t treated fairly in the Bais Din or Court of law. Sometimes this isn’t true and the husband just wants to be mean. But unfortunately, a lot of times it is. The Bottey Dinnim and Courts aren’t always where Justice takes place. To say that nowadays the Bottey Dinim have the right to enforce their Psakim with violence, is showing that you are extremely ignorant of what happens in our “Justice” systems nowadays.
The way it appears to me is that the father of the wife used the Bais Din in EY to throw the guy under the bus. He then hired henchmen to do his dirty work. I believe that this is a good possibility, even though of course I can’t know 100%. But for s/o to claim that anyone can take the law into their own hands without even taking into consideration of this possibility is putting their heads in the sand!
