Should I say something next time?

[downbeatplumb]

My sister who is has been married for 12 years now is married to a guy who can be a dickhead at times. However, something peculiar happened at my grandmothers funeral. First, while I was with them in the car driving somewhere to eat (my parents went back to the hotel) they started talking about who gets what since my grandfather had already passed and now my grandmother would have passed thus leaving things like the estate up for grabs and to be divvied out among my Dads family. That in itself was quite the headache for my Dad since he really did not care what he gotten and so forth. But my brother in law kept going on about how my Dad is doing everything wrong and does not know what he is doing and that he should let him handle everything from selling the house since apparently now my brother in law knows how to sell a home that's worth a few million. 

Then, he has the gal to talk about what he will get when my parents pass away. I can tell you this really bothered me even more. He then starts to complain about how one of my brothers who is a bit slower will get more than everyone else. My brother in law claims he has gone through my parents will and knows their finances. By now I am just fuming on the inside. Mostly because I do not like it when people attack my parents like this, and also I could care less with what happens when my parents pass away. And I am not exaggerating when he claims to know about my parents finances. He says he has gone through their stuff and found out how much they pay in taxes and how much they own when it comes to worth net worth..etc. I stayed silent, mostly because in the past when confronting him about things he is clearly bull shitting about he really won't care and it just causes problems. But I just sat there in the backseat just trying to hold my tongue. I feel like a coward for not speaking up though.

I am just wondering, should I bring this up to my parents despite this being almost a year since it has happened? I think something else to consider is that their relationship with my parents has become quite strained as of late. We had them over for Christmas dinner, and a week later they told my parents straight up that they did not have a good time. They then threw out the excuse that it was because I yes, ME made them uncomfortable because I have been doing bad things like watching porn and such. They claimed to have saw me doing that when we were on vacation the summer before. But i can't not tell you how untrue this is. I never did that when we were on vacation. And if I even do i do it alone, in my bedroom in my home. (TMI? lol)

I should also mention they have somehow turned my sister against my parents, secretly. Her and her girlfriend are now part of their little gang and talk shit about the rest of my family behind our backs.

I am just not sure what I should do in this situation.

I may be the wayward family member that is open about his lack of belief in a God in a family that believed in God, but at least I respect my parents and don't talk shit about em'.

Get a nanny cam and get him to open up. move it to DVD and show the DVD as part of Christmas festivities.
