Definitely not the correct place to post this, but I figured someone who knows local laws might be able to help.

My sister in law is an alcoholic, and is in serious denial. She drives drunk constantly. Usually after binging throughout the night then heading off for work in the morning. It has gotten to the point where myself and my partner are ready to do something about it.

We are potentially ready to get the police involved, but are really nervous that this might destroy our relationship with her if she were to find out. It is an option though.

Another option is honestly just fucking with her car. I wouldn’t know where to begin with this though. I’m not a car person. If anyone has any ideas how I can fuck with her car so she can’t drive it- please let me know. It needs to be as discreet as possible
