Why? Wouldn't be better to freeze account and cooperate with police.
Funds - coins have been deposited to BTER trading account and this person seems he would like to sell this coins. You are not police, judge or jury. Just cheap Bter advertising.
I respect klee, but people are acting very hypocritical. If newbie would lost his funds in a similar way, you would all just say it's his fault and that he is stupid. He would never get his funds back.
Please don't get me wrong.
I don't see why there would be a need to co-operate with the police at all? From what I saw on Twitter klee's account was hacked and now BTER found the hackers exchange account where klee's NXT/BTC was transferred to. If klee verifies his identity and the community supports it then they could just hand the funds back to the rightful owner. If you read on the NXT forums klee seems like a trusted member of the community, not just newbie who has no credibility.
If BTER were to co-operate with the police it would take months before the case gets resolved, and they could argue some excuse that they can't verify the rightful owner etc. (most people don't understand Bitcoin let alone NXT) and all funds would be transferred over to the government.
