NCIS: New Orleans

Hey! Get your hands off!

I'm exercising my First Amendment right!

What were you gonna do with this?

You can't detain me!

What? Interesting venue for our third date.

I didn't think beignets at Café Du Monde would impress.

Welcome, one and all, to the military...

...the world's best engineers and scientists.

This definitely isn't doughnuts.

No, it's not.

Oh, no!

Oh, God.

Ma'am, what's the problem?

Call the police. It's a bomb.

What? Did you just say...? Leave!

Get out of here. I'm gonna help.

Everybody! We have an active bomb

on the premises. Please clear the area!

This thing will go off in less than a minute, and who knows

how much damage it can cause.

Like I said, there is an active bomb on the premises!

Please clear the area as quickly as possible!

I'm a ballistics expert,

but I have explosive experience.

I think I can deactivate it.

You have any experience?

One day training. How can I help?

Okay, the key is to separate the blast cap from the timer.

It looks like there's a couple false wires.

Yeah, somebody knew what they were doing.

I can separate the elements to give you a better look.

This is ridiculous. Let's run.

Most of the wires are yellow and red,

but-but there's a single green.

Looks right to me.

That's my vote, too.

Here goes nothing.

Holy crap. I think that worked.

Hey, Ben,

you know how you said you wanted to impress me?

Well, consider me impre...

What do we know, Hannah?

Device went off at 10:04 a.m.

Two dead. Seven critically wounded.

I was told there were Navy victims.

Seaman Apprentice Ben Frisell, DOA.

Seaman Apprentice Neila Diseris survived.

They rushed her to Mercy Hospital.

And the other DOA?

Yeah, Dr. Alice Logan.

She was on-site to present a seminar on modern ballistics.

According to witnesses,

she was attempting to disable the device.

Why would she do that?

I believe she thought she could help.

According to NOPD,

there were close to 1,000 people in attendance this morning.

Tragedy could've been much worse if our Sailors hadn't helped

clear the room. Anything else to follow up on?

There was a protest group here, Survivors for Peace.

Lasalle and Gregorio are questioning them now.

See if they found anything.

I'm gonna join Sebastian and Loretta.Okay.

Over the years, I've worked more than my fair share

of bomb scenes. It's not the chaos that gets to me.

It's the smell, right? Ah...

The heavy chemical residue

leaves a metallic taste in your mouth,

and the human element...

It's like cooked meat. Stays in your clothes for days.

Does that smell give us anything to work with forensically?

Well, there was a benefit to the explosion being inside,

there's more particulates in the air.

I'm getting cordite and sulfur.

Can it help you identify the materials used in the device?

Yeah, and how they might behave.

So some bombs are, uh, directional.

You've seen a Claymore mine?

The ones that have "This side toward enemy" printed on them?

Yeah, well, this device had a similar blast pattern.

It was intended to explode in just one direction.

Unfortunately, it blew towards the door,

injuring anyone who was still trying to flee.

Suggests a targeted attack.

Ah, it's too soon to tell.

Able to collect any remnants of the device?

Nothing useful, not here at least.

Where else would it be, Sebastian?

The force of the explosion was concentrated

towards the door.

Notice anything interesting?

Yeah, there's a void here.

Yeah, right where Seaman Diseris was standing

when the device detonated.

According to the EMTs, she was hit with a lot of shrapnel.

Some of which may be valuable evidence.

Get to the hospital.

Collect whatever you can.

Sorry to keep you waiting.

Lot of folks to interview.

Not a problem. I know the drill. Been through it before.

A woman we interviewed earlier told us your daughter

was the victim of a mass shooting, is that true?

Yes. She was 18.

Sorry for your loss.

I'm not the only one.

Everyone in my group has lost someone important.

Your group's named Survivors for Peace.

Travel around the country

staging protests against gun shows.

We're not staging anything.

We attempt to engage our fellow Americans in dialogue.

Anything else you engage in at these events?

My daughter was shot five times with 300 PRC rounds.

Designed for Special Forces.

We're trying to bring attention

to the destructive power of these modern weapons.

Incidents like this morning's brings a lot of attention.

Our entire platform is about getting rid

of weapons like this. We'd never use one.

We understand, but there are dozens of others in your group

who have a different opinion.

Yeah, like a man that was arrested before the bombing,

appeared to have a gallon of blood

in his possession.

Brock O'Driscoll is not a member of my group.

He's a bottom-feeder.

He's trying to use our suffering

as a way to make a name for himself.

And how exactly does he do that?

Check his social media.

He'll do anything for attention.

Anything?

My rights are being violated.

I demand to be released immediately.

You're not in my custody.

You're gonna have to take it up with NOPD...

after you explain this.

I don't know what that is.

It's blood, Brock.

It's probably not human blood, but I wouldn't put anything

past you considering your history.

That's not mine.

Officers found it in your backpack.

Assuming you were gonna go full Carrie

on someone at the show.

I don't even know what that means.

Coy's not your play, Brock.

Not after the videos that you've been posting online.

You're a professional disruptor.

You perform childish pranks at public events

for as many clicks as possible.

So is every law enforcement agency in the state.

What can I say?

The public wants outrage.

I give it to them.

What I want to know is what made you step up your game today.

You think I planted the bomb?

Why else would there be a line of federal agents

waiting to interview you? No.

No, no, no, no. No, you got me wrong.

See, I-I create spectacle, okay? Not-not carnage.

Okay, nuance is lost on us, Brock.

You're gonna have to do better than that. Look,

there was someone else.

He went into the museum with a backpack.

He came out a minute later

without it. He ran right into me.

No one else noticed it?

They were noticing me.

Okay.

I'm gonna need a full description,

and you better hope for the both of us that you have a keen eye

for detail. Go.

This is a composite of our suspect

Brock O'Driscoll claims ran out of the arms show

minutes before the device detonated.

We're running it against security videos

and facial recognition.

Could be a wild goose chase.

O'Driscoll covering his ass.

Could be a lot of things.

But we got to follow every lead.

We got two dead,

a Sailor fighting for her life,

seven critically wounded.

And considering the size of the device,

we might've been looking at a lot worse.

Yeah. We're six hours out from the bombing.

There's 300 federal agents and law enforcement officers

working the case. What do we know?

Major arms show in the heart of the city.

Working theory is some kind of terrorism

or political statement. Yeah, but there wasn't

any chatter,

according to the FBI, before or after the explosion.

Every weapons manufacturer in the country was at this event,

but the bomb was found at Dr. Logan's booth

on her table. You thinking this was a targeted attack?

I think we need to deep dive our victims,
