Florida neighbors becoming increasingly aggressive

Location: Central Florida

The question is, if I have this couple's name and info (which i was able to find when seeing if either had a past record) would it be an issue if I called and asked what their deal is? Im scared for my parents with the increasing aggression and would like to see if I can get them to back off.

My parents still live in the same home I grew up in (which is to say that there's always been peace, never any issue). It's not an HOA community. A few years ago, a middle aged couple moved into a newly built home diagonally behind them. No kids. My parents don't have a fence and those neighbors put a white, completely private fence up - obviously totally fine.

The issue is, that couple can be heard screaming at each other frequently and they have 4 large dogs. Over the past couple years, the woman has been finding ways to peer over her fence into my parent's yard and stare. That staring turned into yelling about my parent's dog when hes swimming. Now, she's peering over the fence and started calling my mom a fat-ass and saying "no one wants to see her fat fucking ass getting out of the pool" completely unprovoked. She then walked her larger, aggressive dog outside of her fence after my mom ignored her and kept trying to bait my parents dog to come after her.

I had her call in to the cops to make a record that this is going on. At a recent family party, she sat outside and kept staring at us over the fence. When the dogs were swimming, she kept making barking and growling noises at them.

I know that we can eventually get a restraining order for the property, but I feel awful for my parents the husband cussed my dad out when he defended my mom.
