Wednesday, The House Homeland Security Committee will hold a hearing relative to last year’s Boston Marathon bombing. Held in Washington D.C., the proceedings are intended to investigate any oversights that may have led to the attack and what we as a city can do to prevent another.

In February we reported that Massachusetts Congressman Bill Keating hoped to move the hearings back to Boston in order to give voice to the victims unable to trek to the capital.

“I think having it here in Boston right before the Marathon was somewhat political,” Mayor Marty Walsh told WCVB. “I didn’t say I didn’t, I said I’d prefer if they could wait until (April 22) to have the hearing.”

According to the Committee’s website, opening remarks will be made by Congressman Michael McCaul (R-Texas), Chairman of the Committee. Four witnesses will then testify – former Boston Police Commissioner Ed Davis, Watertown Chief of Police Ed Deveau, Watertown Police Sergeant Jeffrey Pugliese and Harvard Kennedy School of Government Professor  Herman “Dutch” Leonard.

CBS Boston notes that Pugliese was directly involved in the shootout with both bombing suspects that took place on the streets of Watertown in the early hours just days after the bombings took place. He tackled Tamerlan Tsarnaev, the brother of Dzhokhar who’s currently facing trial, seconds before Tsarnaev was killed.

The hearing is slated to start at 10:00 a.m. Wednesday morning, at which time participants will discuss domestic security changes that have taken place since last year’s tragedy and what still ought to be done. Though CBS contends a recent Homeland Security Report found that authorities may have contributed to the incident through negligence, the Boston Globe points to a report published by Harvard that says years of preparation led to solid security responses.
