AMNA NAWAZ: The Trump administration's federal# takeover of Washington, D.C., is escalating, with## several people arrested at high-profile locations# and homeless encampments torn down.

Protests also## erupted in the streets last night after the White# House said federal agents would patrol around## the clock and the president himself hinted that# his monthlong crackdown could last even longer.

PROTESTERS: Get off our# streets!

Get off our streets!

AMNA NAWAZ: Protesters took to the# Northwest D.C. streets last night.

PROTESTER: Why are you here?

You're# trying to arresting innocent people.## What's your purpose?

What's your goal?

AMNA NAWAZ: Responding to this show of force,## federal agents alongside city# police now under federal control## running a checkpoint at a busy intersection.

WOMAN: Turn left.

AMNA NAWAZ: Some residents warned# approaching cars to turn away.

Police say they arrested 76 people in the# District yesterday, outpacing last year's## daily average of 56.

And the D.C. police# chief said today that information collected## during these kinds of traffic stops could now be# turned over to federal immigration authorities.## It's all part of a federal crackdown in the# nation's capital launched by President Trump,## citing a crime emergency that# the data doesn't fully support.

DONALD TRUMP, President of the United# States: Crime is rampant in D.C.

It's## rampant in our generally blue-run cities,# and they have got to do something about it.

AMNA NAWAZ: Federalizing the# D.C. police force carries a## 30-day legal limit.

The president# said yesterday he may extend that.

And this morning, blocks from the White House,## another part of the president's plan went# into action, homeless encampments toppled,## and the people who once sheltered there# nowhere in sight.

More visible in D.C.,## National Guard troops activated by the president# as part of what he calls an anti-crime agenda.

For more on the D.C. takeover, we're joined now# by Juliette Kayyem, former assistant secretary at## the Department of Homeland Security.

She's now# at the Harvard Kennedy School of Government.

Juliette, welcome back.

Thanks for joining us.

JULIETTE KAYYEM, Former U.S. Department of# Homeland Security Assistant Secretary: Thanks## for having me.

AMNA NAWAZ: I just want to ask.. have federal agents wearing Homeland Security# gear running a traffic stop with Metropolitan## Police, National Guard troops patrolling# high-tourist areas like the National Mall.

I mean, from your experience, is it clear# what the intention and strategy is here?

JULIETTE KAYYEM: So there's# two different pieces of this.

One is, federal law enforcement agencies,# FBI, HSI, Homeland Security Investigations,## working with, in tandem Washington,# D.C., police.

This is -- it's unique.## It is not clear what their -- what the federal# agents' authority is.

It is not clear whether## they have -- they can arrest for a petty# crime, since that's not a federal crime.

And I think there's a lot of confusion# about what their authority is.

Right now,## we just see them walking around.# The second is what we call presence## patrols that is being done by the# National Guard.

Presence patrols are,## we are here.

We're an army or a unit# that is making its presence known.

It is not generally used in the military# because there's really no task or purpose## for it.

There's no mission for it.

It's# just simply that we are present.

And,## in both cases, the concern is, because# the mission isn't clear -- ending crime,## getting rid of poverty, all of those things# are sort of nebulous in terms of what are the## tactics that would justify federal involvement# -- it is not at all clear whether the mission## will maintain or you're going to get mission# creep over the next couple of days and weeks.

AMNA NAWAZ: Juliette, when the president# launched this effort, he talked about## ramping up the use of force, right?

He said# that the D.C. police are now allowed to do,## in his words, whatever the hell they want,# promising forces would hit harder now.

Does the presence of federal forces,## federal agents somehow allow for# more force in these interactions?

JULIETTE KAYYEM: It doesn't.

I mean, and, to be cle.. engagement is.

If someone spits at a police# officer, they're not allowed to shoot them.## That is not -- that's not permissible.# That is not an appropriate response.

The president talks like this as a signal of# authority, aggressiveness, and some would even## say totalitarianism, or at least the usurpation# of local control by the executive branch.

Where I worry is, of course, with a undefined# mission and unclear integration of these forces## with these forces with now the National# Guard, you will get mistakes.

You will get## people working and acting outside their# authority.

You will get responses to## First Amendment activities, including lawful# protests, that violate the First Amendment and## undermines people's rights to free speech.# You're allowed to criticize this activity.

And let's just be honest here.

This# is a lot of people who are now not## looking and not investigating fentanyl# and domestic violence and terrorism.

AMNA NAWAZ: Juliette, the president has said# he wants to extend this authority in D.C.,## possibly even to other cities.# What are the implications of that?

JULIETTE KAYYEM: Well, there's going to be# the legal implications.

D.C. is unique.

It## has a home rule aspect to it.

What would be the# legal authority for the president to do that?

There's also the political issue,# of course.

Is this an attack on## Democrat -- Democratically run cities,# blue cities, blue cities in blue states?## And is that the appropriate use of the# military or federal law enforcement?

But I want to take a step back and say my# concern is, is this is working?

We have## decades of research about what works in this# arena, especially in terms of policing.

It's## community policing.

It's outreach to communities.# It's engaging people and neighborhoods that might## have crime to work with them to minimize# crime.

This is exactly what D.C. has done.

A federal military or federal law enforcement# overlay seems many steps away from that.

AMNA NAWAZ: Juliette Kayyem of Harvard's Kennedy# School of Government joining us again tonight.

Juliette, thank you.

Good to speak with you.

JULIETTE KAYYEM: Thank you.
