In the US, the police can stop anyone and seize whatever they have on or with them, without any need for even suspicion of a crime. Usually they just take cash and move on. Then the victim can try to get his money back through the courts, which will cost money and may take years. Of course, given the usual level of integrity associated with government employees, abuse is widespread. As of 2014, it has come to the point where the cops are taking more than the robbers.
Between 1989 and 2010, U.S. attorneys seized an estimated $12.6 billion in asset forfeiture cases. The growth rate during that time averaged +19.4% annually.
In 2010 alone, the value of assets seized grew by +52.8% from 2009 and was six times greater than the total for 1989.
Then by 2014, that number had ballooned to roughly $4.5 billion for the year, making this 35% of the entire number of assets collected from 1989 to 2010 in a single year.
Now, according to the FBI, the total amount of goods stolen by criminals in 2014 burglary offenses suffered an estimated $3.9 billion in property losses. This means that the police are now taking more assets than the criminals.
Taking into account the shootings, it is clear that the cops are now way more of a danger to the citizenry than the so-called criminals.
