Who guitarist Pete Townshend was arrested Monday on suspicion of possessing indecent images of children after police conducted a search of his London home and office. However, the 57-year-old rocker has not been charged with a crime. Under British law, suspects can be arrested first and charged later. Over the weekend, Townshend admitted that he paid to access a child porn site, but said he only did so for purposes of research. "To fight against pedophilia, you have to know what's out there," he said. "If I did anything illegal, I did it purely for research. I am not a pedophile."
