Not really. Every country has a nonzero number of criminals. It's entirely a matter of the risk/reward tradeoff. A small consumer item over $10k is well into dangerous territory.
If it is an electronic payment, I'm not sure how completing the transaction in front of a police station will help any. Well, it will help the buyer to see it working, but the seller gets no additional protection besides seeing "a person."
That's not the point of going to the "police safe exchange zone".
The point is to hopefully prevent the possibility of the buyer showing up with a .38 in hand, and demanding to be given the easy to fence "item" unless the seller wants to get a .38 slug embedded in their gut.
The risk of a "hold up" increases with dollar value and with items that are easier to fence.
