Voter intimidation against whites in Donaldsonville?

My dad called last night to tell me about his voting experience yesterday.

He's white and lives in Donaldsonville. When he was in the voting booth, the curtain and some sort of rod falls on his head. The workers (most of whom were black) ran to his assistance while getting inside the booth with him while his votes are still on the ballot (he hadn't submitted them yet). He said he felt like his privacy was very violated and because everyone was right there able to see his votes, he quickly just hit the "VOTE" button to submit what he had and erase them.

He overheard the workers saying "it happened again", in regards to the curtain falling. He then heard other white voters across town talking about it in the grocery store later that afternoon. I don't know if it happened to black voters but from what he heard, he only heard about it happening to white voters.

It could just be innocent but it sure sounds sketchy to me. I told him he should report this to the SoS office but he doesn't want to. What would you all do in this situation?
