I am doing computer this line, recycling some second-hand computers and so on, that is, the collection of things are stolen by others, this is not illegal?

If you know that the price of things high people still sell at a low price (the suspicion of stolen goods), you also acquired then is illegal, belonging to the sale of dirty, was caught (whether the thief was caught or the owner of the loss of recognition of the lost property) you pay to buy the money and things will be confiscated, the things may be returned to the owner of the money is gone. It also depends on the value of the case, the case value is not much if nothing, it is the money lost.
