A snippet from the Guardian link (left leaning newspaper, and by far the most liberal)......
"The hoodie was everywhere during the UK riots. But how did a comfy, utilitarian item of clothing become the ultimate symbol of exclusion and menace?"
Feared, derided, misunderstood and still resolutely un-hugged, the utilitarian, hugely popular sportswear garment, the hoodie, has staged a comeback against a backdrop of pyromania and rioting. Worn by millions every day: a generation's default wardrobe choice was transformed into an instant criminal cloak for London's looting youth. It may be more newsworthy now, but the hoodie and the folk devil it represents have been with us for a long time.
In 2007 I reported from the riots that set the Parisian banlieue suburbs alight, and interviewed teenagers who had been involved with or close to the events. Most of them wore hoodies, along with the other staples of the 21st-century, hip-hop redux wardrobe – tracksuit bottoms or voluminous jeans, expensive trainers, baseball caps, black Thinsulate gloves and the occasional bandana.
A year or so later, I met youths involved in gangs around the time of the London murders of teenagers Billy Cox, James Andre Smart-Fordd and Michael Dosunmu. These two groups may have been separated by the English channel, but the uniform was identical, and the hoodie was as ubiquitous as the two-piece suit in the financial centres of Paris and London.
Whether or not David Cameron ever spoke his infamous "hug a hoodie" words, let alone made good on his views, it's true that the hoodie was a political symbol long before it became a policy initiative. All clothing is political in the sense that it communicates a message about how the wearer wishes to be perceived, and face coverings and headgear can be particularly charged: the use of balaclavas by sectarian paramilitaries, bandanas worn across the face, or caps worn low to disguise the eyes, represent a seizing of anonymity and a self-exemption from public identification.......etc.
