Task: Question Generation
Input (English): Passage: A battle-hardened Huntley-Brinkley reporter later said that no military action he had witnessed had ever frightened or disturbed him as much as what he saw in Birmingham. Two out-of-town photographers in Birmingham that day were Charles Moore, who had previously worked with the Montgomery Advertiser and was now working for Life magazine, and Bill Hudson, with the Associated Press.  Moore was a Marine combat photographer who was "jarred" and "sickened" by the use of children and what the Birmingham police and fire departments did to them.  Moore was hit in the ankle by a brick meant for the police. He took several photos that were printed in Life.  The first photo Moore shot that day showed three teenagers being hit by a water jet from a high-pressure firehose. It was titled "They Fight a Fire That Won't Go Out".  A shorter version of the caption was later used as the title for Fred Shuttlesworth's biography.  The Life photo became an "era-defining picture" and was compared to the photo of Marines raising the U.S. flag on Iwo Jima.  Moore suspected that the film he shot "was likely to obliterate in the national psyche any notion of a 'good southerner'." Hudson remarked later that his only priorities that day were "making pictures and staying alive" and "not getting bit by a dog."Right in front of Hudson stepped Parker High School senior Walter Gadsden when a police officer grabbed the young man's sweater and a police dog charged him.  Gadsden had been attending the demonstration as an observer.  He was related to the editor of Birmingham's black newspaper, The Birmingham World, who strongly disapproved of King's leadership in the campaign. Gadsden was arrested for "parading without a permit", and after witnessing his arrest, Commissioner Connor remarked to the officer, "Why didn't you bring a meaner dog; this one is not the vicious one."  Hudson's photo of Gadsden and the dog ran across three columns in the prominent position above the fold on the front page of The New York Times on May 4, 1963.
Output (English): What was the full name of the person that was charged by a police dog?
