That is what THEY would have you believe. Speedy was actually a micro-biologist who had discovered how you could splice human and sheep DNA. The result would be humans could grow a woollen coat in the winter thus not needing to buy jumpers. He didn't actually commit suicide, it was an elaborate set up orchestrated by a cartel of jumper manufacturers. So as to not incriminate their masters the agents who took Speedy out removed all Primark clothing from his house. If you don't believe me check out the leaked inventory of clothing on the web, not one single jumper was discovered in the house and the time of the Police report? 9:11 a.m. Oh yes.
I'll just wait for the movie to come out. You can always rely on Hollywood for educating the world with the facts.
