The Provisional IRA began their London bombing campaign in the early 1970s. In 1973 alone, the Provos successfully planted 36 bombs in London. Their goal in bringing the violence of Northern Ireland to the heart of the UK was to turn the British people against their government and thus push for independence from Northern Ireland.
Trash cans eventually proved to be the perfect vessel for IRA bombs. By using trash bins, they were able to target crowded areas and thus make an impact in the media and get a reaction from the government. In 1991, the IRA planted a bomb in a trash can at the bustling Victoria Station. Two years later, several children were killed in yet another trash can bomb. Londoners at this time faced a constant state of fear that undoubtedly disrupted their lives and safety for over thirty years. The removal of a vast majority of the trash cans in Central London may seem a bit trivial, but it had a profound effect on the sense of normalcy that we value so highly in Western societies.
Although the IRA bombing campaign officially (and actually) ended in 2005, the British are taking steps to ensure that trash can bombings will no longer be an issue. London is set to be the first city to try bomb-proof trash cans. These trash cans, which will also be recycling bins with LCD screens that display travel information and news updates, were developed by British company Media Metrica. According to that company they "weigh one ton each, and were tested in the lifeless deserts of New Mexico for five years to ensure they are completely, totally indestructible, can absorb heat from explosives, prevent shrapnel spread, and extinguish "fireballs."" In the midst of the current economic crisis, these futuristic trash cans may be a ways off, but the fact that they are even being considered is indicative of the past and present times.
