First, no officer takes money for himself.
Second, you never take ALL the money. A representative sample is kept for evidence. You can't blow a bust because of greed.
Third, any money taken is turned into the detective or officer tasked with maintaining the slush fund.
The money is then available for all the officers when the kid needs braces, when the car needs a new transmission, when you're a little short for vacation, etc. When the pot starts getting too big, as it always does, most is divided and distributed before a major holiday. The guys in the tactical units and really jumping precincts could literally buy a car every year before Christmas.
See, Rivenbark was simply a crook, rather than a team member looking out for his brother officers.
