I have a friend who has an ex. He is extremely violent, and has harmed her physically on more than one occasion. She has pressed charges, he gets time, and he gets out, he waits a while, and he does it again. She has a child with him. She is more than terrified he will find her when she is alone, and will potentially take her life. I want to help her protect herself. Looking online, I found some things I want to purchase for her, a tazer that looks like a cell phone and has a locking mechanism so it will not go off by accident, a book abt defense for women, and a 3 in 1 strobe light pepper spray loud noise emitter. Tazers are illegal in her state. It is a crime of the 4th degree. If he tried to kill her, and she used the tazer, what happens? Is it worth saving her life for the punishment?If not a tazer, what do you recommend? I know he has walked through restraining orders before, he doesn't seem to care about punishments, he verbally abuses his child, it is really bad. He does not live in the home, but he is allowed phone calls to his daughter, and has reduced her to sobbing while yelling at her and telling her he hates her. It's really bad. Thank you for any help.
