 If to consider this crime from the point of view of the organization
and carrying out, ideal it is impossible to call it in any way. But as
children were lucky as it was lucky! On February 25, 2009 three
robbers went down on a rope ladder through a window in one of
jewelry stores of Des Westens, the second-large shopping center in
Europe. Everything, at first sight, passed ideally: criminals weren't
detained on a crime scene, they managed to disappear safely with
jewelry which total cost exceeded 5 million euros. But there was
one big "but": one of thieves on imprudence left a glove in shop
from which DNA was succeeded to allocate polices. It would seem,
theft was opened – it was necessary to detain "rasteryasha" and its

the airport of Portland of the State of Oregon aboard the
plane making flight to Seattle somebody sat down Dan
Cooper. I called up to myself the stewardess, I ordered
whisky and I told to the girl a note with the message that in
a portfolio there is a bomb. Payment of $200 000 was the
main requirement of the criminal in exchange for safety of
health and life of passengers and crew. Also Dan Cooper
demanded that provided him 4 serviceable parachutes. The
authorities you made look fat all requirements of the
criminal, having transferred him money and parachutes at
the airport of Seattle. Right after repayment transfer the
criminal released all passengers and ordered to the pilot to
fly up and head for Mexico. When crossing by plane of the
mountains located to the northwest from Portland, the
terrorist put on a parachute and was landed. It is still not
known, whether it managed to the robber to survive after a
jump.

6.  3rd place. Robbery in a Boston was
 One more robbery connected with a holiday, one more unsolved
robbery. On March 18, 1990, on a St. Patrick's Day, police officers
approached to the doors of the art museum in Boston, having told I
guard that on a post the disturbing message arrived that robbers got
into the building. The watchman immediately opened a door and
was also immediately imprisoned in handcuffs. It appeared that
under a police form the criminals who decided to rob gallery
disappeared. To the security guard ordered to call on a handheld
transceiver of the workmate who was also held down by iron
bracelets. Only a few minutes later robbers left the museum, having
taken with themselves 13 most expensive pictures among which
there were Vermeer, Degas, Rembrandt's invaluable masterpieces.

detained, pictures in the market didn't appear …
