Doubly so in the UK. Here, the police can presume without proof (and have done so) that any cash in excess of GBP1000 is the "proceeds of crime", and the onus is then upon the owner of the cash to prove that it isn't.

Sounds like a convenient rule for law enforcement to incriminate people when they have a "hunch" about their illegal actions.

When I was 12 y.o. I had that sort of money in my bedroom (years of saving money from my paper route job, and factoring inflation). Of course, I could prove that it was mine, but it seems like the bar is somewhat low if it's set at GBP1000. It's the kind of money that you use to pay to rent a cottage for your vacations, not ludicrous drug-traffic amounts ...
