Each property generates some product. When robbed, it reduces that "inventory of product". When the level of inventory gets so low the Police Line shows up until that property regenerates more product.

It relates to all properties and their inventory level. Right after you collect from your properties the inventory is 0 so another user would see Police Lines until your properties produce more inventory.

There is no "who", just a math formula that determines how fast each property produces products. Search for Properties on wiki and you'll see the "production rates" based on time for each property type.
