This incident took place in Spain; a bank holdup gone wrong turned into a 'hostage barricade' scenario. The Spanish police apparently resolved the situation by allowing the bank robber to 'escape' unimpeded. He was allowed to walk out of the bank in the company of 2 hostages, then police provided him with free access to a motorcycle. Leaving the hostages behind, the criminal perpetrator was permitted to ride away down a clear roadway to make his 'escape.'
This whole incident, shown on CBS television in English, can be seen on this 55-second video clip. The conclusion of this video shows the result of the Spanish planning.
This wouldn't happen in America. Our guidelines are too soft; we treat criminals and terrorists like law-abiding citizenry, we read them their "rights" and then provide them with lawyers.
