The Changes Since 2013's Boston Marathon

The Changes Since 2013's Boston Marathon
The security plan for this year's race will be drastically different from 2013, yet similar to the one put in place the year prior.

It's been two years since the tragic bombing at the 2013 Boston Marathon killed three and injured dozens. Since then, the iconic marathon has changed. 

One of the biggest changes starts with bomber Dzhokhar Tsarnaev. 

"So many people in that courtroom waiting for justice, wanting for justice," CNN's reporter said. 

Tsarnaev was convicted earlier this month on 30 counts, including use of a weapon of mass destruction. That, among many of the other charges, carries a life sentence. 

It's still undecided whether Tsarnaev will face a lifetime in prison or be sentenced to death. Tsarnaev's sentencing begins this week and could last for just a few weeks. 

Since the bombings, tighter security and restrictions have been in place. Boston Marathon race director Dave McGillivray told ESPN this year's security plan is drastically different from 2013, but just slightly different from last year's. (Video via The Boston Marathon)

"Because [the plan] was successfully carried out last year, we didn’t have to reinvent the wheel all over again."

Boston Marathon officials said Monday's race would be a "no drone zone" and they'd be using anti-drone technology to make sure none are flown. 

The 119th Boston Marathon is expected to include more than 30,000 runners and 9,000 volunteers.
