You mentioned being unable to get any information from hospital staff. Did your brother-in-law explicitly instruct them for some reason not to provide any information to other family members?
How exactly was he granted power of attorney? Was your father-in-law capable of signing a power of attorney when he was initially hospitalized, or had he signed a POA or healthcare proxy beforehand? If the latter, did it assign multiple agents and specify any restrictions on how they make decisions? For example, was the brother-in-law listed a successor to someone else in the agreement or are they co-agents? Getting a copy of the agreement will take very little billable time for any attorney. Given that time is probably a factor, and from how entrenched the attitude you've described is by now, it's unlikely that you or the family will be able to talk your brother-in-law into backing down in any reasonable timeframe. Your first step is to get a copy of the power of attorney agreement and go from there.
Speaking to an attorney might seem like an aggressive step in such a precarious situation, with the potential for long-term consequences for the family dynamic. On the other hand, as difficult as it might be to hear, you're probably already at that point. Were your father-in-law to pass away without the rest of the family even being able to hear what's happening from a medical standpoint, painful as it may be to contemplate, it's highly unlikely that anyone in the family is going to be willing to forgive your brother-in-law for it. Appearing to go around him to get a copy of the agreement might be seen as a betrayal, but it's probably going to be less problematic in the long run than the status quo.
I've seen families that have been permanently torn apart during end-of-life decision-making. Be that as it may, some manage to heal. Eventually. I hope that yours will be one of the ones that does so.
