BOSTON (CBS) – The 4th of July is a huge part of the very fabric of Boston, but it’s also a monstrous security headache.

But keeping upwards of a half million people safe isn’t left only on the shoulders of the Boston and State Police, the FBI is also involved.

“The FBI is not aware of any specific threats or concerns relating to the Boston Pops Fireworks Spectacular,” said FBI Boston Special Agent Hank Shaw.

“We expect hundreds of thousands of people to come to the Esplanade to enjoy and celebrate,” said Boston Mayor Marty Walsh, referring to the 4th of July Pops performance.

Law enforcement officials are confident that their security measures for the event are solid.

“We will deploy a multi-layered, multi-agency security plan to maximize the public’s safety,” said State Police Colonel Richard McKeon.

Boston Police Commissioner Bill Evans says heavy trucks and equipment will be used to block streets, in light of several incidents in Europe.

He also said the city’s neighborhoods will not be ignored on the 4th.

“We’ll have plenty of resources down [at the Esplanade] but we’ll probably have more resources in the neighborhoods,” said Boston Police Commissioner William Evans, “July 4th is probably one of our more troublesome neighborhood weekends as far as violence goes.”
