Here's a scenario between my SLI husband and his LSE friend. (Don't think the types are necessarily relevant but I'll include them anyway.)
So they like to buy cool stuff and sometimes sell it. They bought something that sounded cool, but after they got it they were afraid that maybe it was illegal. They were worried about this, but the LSE's son is a police officer and was going to be visiting the next day, so they figured they'd let the friend's son see it and they could decide after that what to do.
My husband came home. In the mean time, the LSE immediately called his son, who immediately went over, and immediately called the local police, who immediately called my husband to find out more about it.
My husband is upset because the guy they bought this from has our phone number and address, so if this guy gets upset, it's us who will hear from him, and he doens't like the idea of someone who had something illegal potentially looking for him here at the house. He thinks the he and the friend could have quietly destroyed the item, or anonymously dropped it off at a police station, or had the son take it with the understanding that it be considered anonymous. He thinks if the guy had the LSE's phone number and address, the LSE would have handled it differently, and that it wasn't fair to tell him one thing was going to happen and then do something completely different without discussion with him.
On the other hand, what the LSE did was probably the best choice as far as what should legally be done.
So who is right. Also, my husband is angry. How angry would you be?
