What can authorities glean from video of Boston suspects?

This is a rush transcript from "The Five," April 18, 2013. This copy may not be in its final form and may be updated.

BILL HEMMER, FOX NEWS: Mark Fuhrman with me now. I'm curious to get your reaction based on the news of the hour and this is significant -- Mark.

MARK FUHRMAN, FORMER LAPD HOMICIDE DETECTIVE: Yes, it is. And, you know, what's interesting about this last 48 hours is that the FBI and the task force for the combined law enforcement task force has been trying to close on the suspects with any hot leads or relevant leads that they could -- that they could acquire, trying to identify a named suspect, the location, so they could close, surveil, perhaps follow and actually control the situation.

And they actually went as far as they could without notifying the public. Now, they believe, I'm sure, that they are hopeful that they lived in the area for whatever period of time, weeks, days, months.

But, I think they believe that they are probably on the move. I'm kind of surprised that they didn't tell the public what the logos on the hats were. Young people, they notice that. They notice the logos and sometimes it means very much not to us as older adults but to kids, where they hang out, what they do, and where they might have got the hat.

So, to me, that's something I wished I would have known.

HEMMER: Well, somebody number two, you see that profile shot, Mark. If someone knows that individual, they can identify him. And can you imagine after this picture went out that they are receiving tips right now.

FUHRMAN: I agree with you, Bill, 110 percent. The prominence of his profile is something that's going to probably be as, you know, his collapse here. If he has been seen or he associates, especially in the attire and the manner in which he is right there, he is going to be remembered and somebody is going to actually call in.

But it is interesting that with that good of a picture, they haven't been able to canvas the area and get anybody to identify him in that general area of Boston. So I think they probably think that they are not from the area and they don't still reside or even hiding in the area.

HEMMER: Mark, I thought it was curious when the FBI agent said if you know them or perhaps their friends or family members, he said it might be difficult but still come forward.

Now, based on your experience has it been picture for people to identify them publicly? Have they tried to hold that information back? Or is this the case where you see the act is so heinous and so wrong and so immoral that you want to identify them and come forward?

FUHRMAN: It's interesting but there is always the problem in law enforcement that loved ones put their love for a relative even if they are a suspect that's committed a heinous act, they put them before the victim. So to convince somebody -- I think he's being nice at this point and later, if you conceal them now you know who they are you are part of crime.

So, this can elevate. I think issue needs to know this. If you aid or abet these people, you help them in any way after now you see these pictures, now you are part of that crime. You are part of that day when the Boston marathon was bombed.

So be advised this is not an avenue you want to go down. The interesting thing about this, bill, is the photographs, they are good but they are probably not good enough for any biometric data base and/or they are not in the system. Same with any DNA or physical evidence they acquired off the bags or the bombs they might not be in the system whatsoever.

And this 48 hours they have tried to pursue all the avenues, to try to close with at least an identity, a name, a location, relatives, vehicles, something. This press conference was pretty sparse when it came to information. They are hoping the public can help right now and I think the next 24 hours you are going to have a lot of tips come in and there is a very good chance that one of those tips is going to lead to at least who these guys are and where they have been.


HEMMER: Mark, thanks. Stand by.


TANTAROS: Mark Fuhrman, Andrea Tantaros here.

Any concerns about vigilante justice? In the days that followed 9/11, you did see some people targeted. Is that a concern of law enforcement?

Now that the public has been asked to provide tips, you know, I hate to look like these two guys here. But, you know, any concerns that they have about people taking this into their own hands?

FUHRMAN: I don't think so. Because I don't think, you know, you look at these two is suspects, you can't jump to any conclusions what their religious affiliation, their race is. I mean, they look like Caucasians, maybe Caucasian mixed with Hispanic or some other race. You can't really tell from the photos.

I don't know how anybody could focus on any one group. There is no ideology attached to these individuals. The FBI doesn't have that information.

So, nobody has claimed this attack which to me doesn't really mean much, because I think even terrorists learn that, if you claim something, all of a sudden there is this big drone coming down at you, you know, firing missiles.

So, I'm not sure that that is something that is really telling here. I can't see any vigilantism here. I think people would certainly participate in reporting. I don't know if they would contact I would advise against it.

GREG GUTFELD, CO-HOST: Hey, Mark, this is Greg Gutfeld.

I have one observation and one question. The observation is it seems like the second guy who seems kind of nervous, judging by his hands. He has his hat on so you can see him, which makes me think that he doesn't care if he is seen which makes me think, he is not from around there. Maybe from another country. My next question is: if parents come forward that would essentially mean he is domestic. And if you don't hear from parents, wouldn't that mean he is international?

FUHRMAN: Well, I think you are right. If nobody comes forward and says I know this guy, whether it's a classmate, a parent, a cousin, a next door neighbor, the guy he buys beer from, dope from, whatever, I think we're talking about somebody that has flown into this country, stayed under wraps in a motel or an apartment -- you know, terrorists they come in. They don't want to be seen.

I mean, they are on to our investigative techniques. So they are going to come in. If they are going to be here to do something they are in and they are out. They don't want to leave any footprint.

If there is a footprint left here I would say they have been here for a while and perhaps they live here. I think you are right, 100 percent.

The guy that seems to be more concerned with his identity being seen, the hat, the sunglasses, he seems to keep his head down more, perhaps he is -- he is the main suspect and this other -- the other suspect with the white hat, perhaps, he is the trainee or the younger, the guy on his first outing.

You know, it's hard to tell. But, when you look at the way they conduct themselves, they don't look very similar in the way they are acting or the way they dress.

BOB BECKEL, CO-HOST: Hey, Mark, this is Bob Beckel.

In your experience of people who have done heinous crimes, commit this kind of crime they have much time to get away. Do they tend to stay in the community or take off and try to get to a border? Try to get some place else or try to find refuge some place with somebody they know in an area?

FUHRMAN: Well, it's an interesting question. Let's just take murder. Let's just take gang murders.

If do you something that is very obvious, heinous, in the media and gets a lot of attention, you are on the fly. You rabbit. You take off, that might be to another state, another city, or another country.

If it's Hispanic gang, naturally, they will flee to Mexico. If it is a black or an Asian gang, they will go to a community that will harbor them and lie about their presence. They might go farther.

I would suspect that in 48 hours, I mean, everybody has been trying to close with these individuals but if they just had a car, traveling at normal speed, they could be half way across the country or to Canada or to the Mexican border. They could be many places. You don't have the ability to close an airport or to notify anybody that first 12 to 24 hours. We really don't know where they are.

KIMBERLY GUILFOYLE, CO-HOST: Mark, you are bringing up a great point. They are bringing in the public right now by bringing in these images and saying they need the help, the delay of game yesterday. We thought they were going to have the press conference. They pushed off on it because they said they had some more groundwork to follow up on.

It tells me that the trail has gone a little cold, that they need the public now. My fear is that these two individuals that have been identified as suspect one and suspect two are no longer with us. Meaning they had a sufficient amount of time, regardless of their original origin, where they are from or if they are from here to get out of country.

FUHRMAN: I would agree. Just look at the first four hours. Law enforcement wants to close in a perimeter to see if they can seal in the suspect. But if they don't do that, by the time you get all the law enforcement and you get organization and you get an operational command post set up is about three or four hours.

By the time that happens, they could be 200 miles away driving just a normal car at normal speed.

So, it's hard to close in that circle, that perimeter quickly if you don't know what you are looking for.

GUTFELD: Mark, question -- second guy walking back. Looks like his leg is buckling, is that just because he has got a backpack or is it because he has got a problem with his leg?

FUHRMAN: I would probably say that that backpack he was probably carrying the heavier of the two devices. I would probably say that, you know, it's probably shifting, you know, and one of those pressure cooker bombs, you have got 10 pounds of explosives, plus the shrapnel, plus the pot.

So, it's probably kind of awkward. It doesn't fit in the backpack correctly. So, I would probably say he is probably trying to act normal and it's probably making him walk just a little strange.

BOLLING: Mark, we will let you go and say thank you very much for your time.
