why did the lord mayor of london order the dogs and cats be destroyed
Great Plague of London Plague doctors traversed the streets diagnosing victims, although many of them had no formal medical training. Several public health efforts were attempted. Physicians were hired by city officials and burial details were carefully organized, but panic spread through the city and, out of the fear of contagion, people were hastily buried in overcrowded pits. The means of transmission of the disease were not known but thinking they might be linked to the animals, the City Corporation ordered a cull of dogs and cats.[42] This decision may have affected the length of the epidemic since those animals could have helped keep in check the rat population carrying the fleas which transmitted the disease. Thinking bad air was involved in transmission, the authorities ordered giant bonfires to be burned in the streets and house fires to be kept burning night and day, in hopes that the air would be cleansed.[43] Tobacco was thought to be a prophylactic and it was later said that no London tobacconist had died from the plague during the epidemic.[44]
London Has Fallen Trumbull's staff have identified a building in London owned by one of Barkawi's companies, which still appears to be drawing massive amounts of power despite supposedly being under construction and unoccupied, and suspect it is Kamran's headquarters. Banning joins the extraction team to infiltrate the building and stop Kamran before he can kill Asher. Banning and Asher escape just before the building is destroyed by the Delta Force/SAS squad, killing Kamran and the remaining terrorists. Marshall has worked with British authorities to restore London's security system and, discovering that MI5 Intelligence Chief John Lancaster (Patrick Kennedy) aided in Barkawi's attack, she kills him. Meanwhile, Trumbull contacts Barkawi to tell him that his plan failed, and then to look outside, moments before the building is destroyed by another drone strike, killing him.
