i cant guarantee anything, at all, including being able to defend yourselves from a sexual predator or an assailant, but try calling the police (NOT 911), and asking for an officer, i suggest googling your town and append the word police to the words your searching (ie if you live in brookhaven new york you would type in “brookhaven new york police department”), and ask to speak to an officer. ask them to suggest a martial arts school, and pay for lessons
martial arts isnt flawless, but after about 2 years you can defend yourself pretty well.
