Police plan to use bomb-sniffing dogs and wide-ranging video surveillance as part of a revamped Rose Parade security plan developed after the Boston Marathon bombings in April 2013, according to ABC News, Pasadena.

Police officials report that the Pasadena Police Department has been working for month analyzing national tragedies like the Boston Marathon bombings, and officers have negotiated with business owners for full-time access to private security cameras.

Police Chief Phillip Sanchez urged the hundreds of thousands of expected spectators to be vigilant, and to report any suspicious activity to law enforcement officers. The department has spent months working with businesses along the parade route to encourage them to tell their customers that if they “see something, say something.” Sanchez also says that 1,100 to 1,200 uniformed and covert officers will patrol the parade route, and more bomb-sniffing dogs will be used.
