A history of pressure cooker bombs

Pressure cooker found at site of Boston Marathon explosions

In keeping with CBC's penchant to promote Islamophobia and do Israel's dirty work, the article strongly suggests that it is LIKELY the bombing was the work of a Muslim terrorist.  It does not come out and say this, because there is no evidence, but it makes a valiant effort to SUGGEST it to be the case.

The article is full of references like the following:

Instructions on how to make such a bomb were featured in the first issue of al-Qaeda's English-language magazine under the headline, "Make a bomb in the kitchen of your mom."
Inside a pressure cooker bomb. (Duk Han Lee/CBC)In these instructions for making improvised explosive devices, or IEDs as they are known in the security world, al-Qaeda's "chef" claims "the pressurized cooker is the most effective method."
The bombs are made by placing an explosive material inside the pressure cooker. The al-Qaeda article recommends military-grade explosives like TNT, C4 or RDX.

Then there a list of pressure cooker bombs used by Muslims:

In 2010, Faizal Shahzad, a 31-year-old Pakistani-American, attempted to bomb Times Square in New York. He had three explosive devices inside his SUV, including a pressure cooker bomb, but they failed to detonate.
U.S. army private Naser Abdo, 21, was arrested in 2011 and charged with possession of an unregistered destructive device.
Among items police seized from his hotel room were two pressure cookers, six bottles of smokeless gunpowder and a copy of "Make a bomb in the kitchen of your mom."
One of the bloodiest incidents involving these devices was on July 11, 2006 in Mumbai, India. Seven bombs went off on commuter trains, killing 209 people and injuring 714 during the evening rush hour.
More recently, in February, a pressure cooker bomb exploded inside a restaurant in northern Afghanistan, killing five people.
French police have twice managed to prevent the use of pressure cooker bombs. Ten Islamic militants were convicted for planning to blow up a market in Strasbourg on New Year's Eve 2000.
And during an investigation into a grenade attack on a kosher market in a Paris suburb on Sept. 19, 2012, police found bomb-making materials, including a pressure cooker, in an underground garage.
They blamed a network of Muslim extremists. Police took seven suspects, all born in France, into custody.

The CBC article was billed as a history of pressure cooker bombs, but it was a very skewed history. While it makes much of the al Qaeda article, it completely fails to mention the FACT that pressure cooker bombs figure prominently in websites and publications of right-wing extremists in the United States.

Moreover it fails to point out that, although the perpetrators are unknown, it is quite possible that the marathon bombing was done by American right-wing extremists, because it was done on US Tax Day, which is also US Patriots Day, and Muslim extremists are more likely to attack a target of political significance than a sporting event.
