I'd start looking for an attorney who's familiar with elder abuse situations and can tell you about your options. If you can gather the right evidence, something can be done.
What does this even mean? Being concerned your dad may fall for scams doesn't mean you should talk to an elder abuse attorney???
1) Someone elderly being scammed by randos is not elder abuse.
2) if there is a scam your "elder abuse attorney" is not going to be able to do any more than the police considering the vast majority of these scams are from overseas.
