it's not that they don't care as the effort put in and the low chances of a conviction make them not look into it. these cases are hard to make and take a lot of resources/effort since it goes across state lines and multiple jurisdictions. if the scammer was all done in state it would be much easier for them to be arrested and hopefully convicted.
that's good you had local PD check on it.
hahaah yea I got one of those too, after I had been emailing back and fourth with "her" for a few says acting like I was interested in buying from her.
who ever they are they have an account here and watch the forum non stop, I think they get our emails from seeing what our profile has on it. she emailed me after I made a post saying only "im sent" about a Sig suppressor that I had already paid for and talked with the seller on the phone.
