This story is pretty wild. Here’s a hopefully somewhat accurate summary, as I understand it:

Basically a family signed a contract with a local lego store to put sell their lego collection out of the store and the store would take a commission for the sale. New owners come in and force previous owners out, then refuse to honor the family’s contract and claim ownership of their $200k worth of lego sets. This youtuber gets involved and the local police goes after him.
