I know someone that has POA for both of her parents. She has alienated her 3 siblings. . She talks about her parents dying constantly. Can I reporo?

My cousin wants her parent's money! I am sure there is some mental elder abuse going on. She makes them choose between their 4 children. If her sisters come over there are screaming fights that embarrass her parents. She secretly videotapes everything that goes on inside their home, with her cell phone. She does not live there. She tells everyone that will listen about old fight problems I don't know if they ever existed. People she should not tell family problems too because her parents had a business they sold. The new owner asked for some Covid relief from the loan her parents were carrying, I wrote the letter for her. Next thing she told me she called the new owners and said she told them all her family drama. I asked why? She said they had a right to know. I know her parents have an attorney and who he is. But, I don't want or need any problems. Is there anything I can do without making it my problem? I am having a hard time standing from the outside knowing who will be hurt.
