We should help to empower people to defend themselves before they become victims, either for the first time or for the 50th time. There are lots of ways.
- Teaching them how to recognize the patterns of dangerous people
- Escorting them when it might be unsafe otherwise
- Help them create distance between them and their abusers
- Encouraging self defense training and accompanying them to it
- Help them secure their home against intrusion
- Let them stay at your place for a while when things get too hot
It's really not that hard to think of ways that don't involve throwing potentially innocent people in jail. You can also just ask people what you can do for them. They probably know already and better than you do.
