Writing minutes is useful but has its limitations.
A few years ago I worked with two technically brilliant but somewhat unpleasant guys.
After a while I realized it was a good idea to write down everything so I made sure I coukd always point to a mail or something.
Turned out even that had its limitations. At one point we discussed something and I ponted the older one of them to a mail where I had described it. His answer:
Sure, that's what you wrote but not what you meant.
Yep, seen it all... However for me personally the most effective is just doing my own notes and storing those with the meetings etc. If people want to frustrate things then they always can but this seems to be the safest way to protect yourself and your colleagues.
You've made a cardinal mistake of not sharing the minutes right after the meeting or, even better, as a last point of the meeting itself. Would that happen, you could reply: "Well, this is what you saw and accepted before."

I left not too many moons later.
