Husband wants to hookup with some guy who’s been in Jail?

Husband and I are open and he told me he is inviting this guy over on Friday night. I asked him who he was so then I go and lookup his name on public databases. Turns out he was arrested 2 years ago for taking pictures of guys in public bathrooms and this was going on for years lol. Cops searched his phone and found hundreds of images.

Do I trust this dude ? Am I being unreasonable telling my husband I don’t want this dude in our house. He is making it seem like it’s no big deal. I looked up his court case and basically he plead guilty and then did a couple days in jail and fines.
