Where did the explosions come from?

According to this video, an eye witness claims the explosion came from a manhole.

According to this report, it didn't.

Considering that there were 2 explosions, is it possible that one of them came from a manhole?

What about this woman who supposedly put down a large bag and her purse and walked off and left them?

Is the place in front of the window the site of the explosion? Why is the glass blown out toward the street?

Why is the glass blown out toward the street?
http://www.howstuffworks.com/blast-resistant-clothing1.htm
"Blast wind: At the explosion site, a vacuum is created by the rapid outward movement of the blast. This vacuum will almost immediately refill itself with the surrounding atmosphere. This creates a very strong pull on any nearby person or structural surface after the initial push effect of the blast has been delivered. As this void is refilled, it creates a high-intensity wind that causes fragmented objects, glass and debris to be drawn back in toward the source of the explosion."

Given the conflicting reports and that neither of them establish which bomb they're referring to, I think it's possible. This image says to me that at least one of them was on either on a manhole cover or a sewer grate of some sort:

It's hard to tell that the bad is gone in the blurred image, it honestly still looks like it's there. We don't have a great view in the photo at the second link either. Regardless, I don't think this bag matters at all.

It looks like there's glass both inside and outside. I imagine if the blast was not very powerful and simply shattered the glass it would fall in place(thus ending up both inside and outside of the frame).

I think this image proves that the brown bag was not related at all, this blast epicenter is clearly back from the curb a bit.

Further, I've seen and heard nothing about any manhole covers being displaced. If a bomb was in a manhole how did the shrapnel or even the blast wave exit to do damage without blowing the cover off?
 
based off of color bubbles in the blur, id venture a solid bet that it IS still there, right up against the damn mailbox.

these bombs are/were very small and weak. they were LOW explosive, meant for maiming. that means weak shock, weak displacement.

Perhaps I missed something.....This report from "The Sun" (a fairly poor source of information), does not really say anything about a woman putting down a large bag and her purse and walking off and leaving them.

I think we've already established that the official media is no more credible than the alternative media.

You can wait for the media to tell you what happened or you can do your own research. It's up to you.

What is "official" media? How does it get to be official?

I get confused with CT's. Is the Sun, a Murdock run paper now a reliable source of information?

Propaganda is disseminated by releasing credible information through unreliable sources and false information through reliable sources. What do you see happening?
 
In journalism, if it has an editorial department, that makes it official, as opposed to a blog, where you can say whatever you want and no one is editing you.

http://www.ads-on-line.com/samples/your_publication/chapterone2.html

So the blog at http://www.breitbart.com/ is official? They have a staff of people who edit and review their content. Does that make Metabunk part of the official media? I have seen where Mick has edited the postings of individuals for not following policies.

I don't claim to know everything, and I don't claim to have the last word on what makes things "official," but in some industries you need a license before you can conduct business. Journalism is a self regulated industry. You don't need a license to be a reporter or a writer or an editor or a media mogul. The technology has blurred the lines of what's possible, so you no longer need a building full of printing presses to put out a publication to reach millions of people.

A news source is considered legitimate if their editorial content is separate from their commercial content. Everything else is blurry.
 

Note what appears to be a blast mark just to the right of the window front.

Yet you are using them to prove your case. You are also using the Daily News, the Washington Times and a radio station. Why are they credible? Because they agree with you?

So it's like the famous quote about pornography "I know it when I see it"?

I'm not proving anything, I'm trying to understand what happened.

All this talk about "official" media seems to have derailed the real question.

You claimed that a woman placed a bag and her purse on the ground and walked off and left them. What is your source for this information? In particular, what evidence do you have that she walked away from the bag after setting it down?

If none, then all you have is evidence that sometimes, when people have been standing for a while holding bags, they set the bags down. This can even happen in areas where a terrorist attack is about to happen.

Is this what you refer to? http://kritterbox.com/Thread-Suspic...se-On-Trash-Bag-Boston-Marathon-Bombing-VIDEO

The video presenter constantly refers to the larger bag as "trash". how does he know that it contains trash? It seems equally possible that the larger bag belonged to the individual with the smaller bag (described as a "purse") or one of the other people close by, who may have been acquaintances. In that case the placing of the bag would not be unusual. Whatever the larger bag contains, placing the smaller one on top would keep it within easy reach.

There is no time stamp. These are still images. We do not know how much time elapsed between the before and after pics. Nor do we know how long the small bag was on top of the larger one....it may have been placed there only for a few seconds while the bag carrier carried out some minor task that required two hands.

There is no evidence from these pictures that she "walked away". Would you please point out where you saw/heard this claim?
 
There are other photos with the bags still there and the woman is gone. Maybe she came back later and picked them up. I'm comfortable with the FBI reviewing the incident, I was simply bringing it up. My point is that it's not clear where the blasts came from, if you have more information or if you're a blast expert and would like to comment, this is a discussion forum.

Two bombs were placed at the finish line of the Boston Marathon, killing and injuring innocent bystanders. What is it that you are trying to understand?

Which other photos do you have in mind?

Surely you don't think that we should just take your word for it that other photos exist?

I think Peter is absolutely correct here.


Having a look at some of the photos, the blast scorch-mark on the sidewalk (right bottom) would explain why the right-hand second story window is shattered while the left-hand second story window remains. (It is still visible with debris damage in the lower right corner).


Also, the left window (bottom) still has the inside glass in place, as you can see by the reflections of the emergency crew in the picture below and would have been first to blow out had the detonation occurred inside. (bottom picture of this link)

Additionally consistent is the damaged "Lenscrafters" sign outside of the building that would have been protected by the structure if it were an inside blast.

Note the "blast seat" with the arrow. X marks the spot.

Wow that's quite a different spot.
Wonder what the mark in the other photo is? Maybe something caught fire from the explosion.
 
That mark is not there is photos immediately after the blast. It's something else.



The bomb went off in the middle of the area covered in blood.



The windows were shattered by shrapnel, and fell straight down and spread on the ground.

Can't find any testimony or pictures that relate to the woman walking away other than the title of this You Tube vid http://www.youtube.com/watch?v=BBup3veCkCI which says "Suspicious Women Puts Purse On Trash Bag And Leaves It- Boston Marathon". but the stills in the video do not confirm that anyone left the scene. Also in one of the pictures a woman is seen holding the bag, this does not necessarily mean she is putting it down, she may have put it down previously, and in that image is picking it back up, or is merely holding it having picked it up at some time before.

Without some confirmation, it would seem that this person (allegedly) planted a bomb and then stood right there while it went off!.....In my opinion this is a red herring and neither this individual nor the bag(s) have anything to do with the blasts, which suggests that this was not the point of detonation.
 
Among the pieces of evidence collected from Boylston Street during the past week was a tree that Dzhokhar Tsarnaev may have leaned against before the bombing, according to a source who receives regular intelligence briefings on the Boston bombings. The source said the tree -- located at the site of the second blast -- was removed along with the surrounding grate, where the explosive device's circuit board was found.

http://www.cnn.com/2013/04/22/us/boston-attack



There's blood in front of the trash can (where the lady's purse was) and also behind the trash can

After the tree has been removed.





Where the bag was.


So they thought the tree was important enough to remove it. Very interesting.

Tree would have fragments of shrapnel embedded in it. Taking it away to get them out would be sensible.
 
In this image you can see that the crush barrier is wrapped around the mailbox. does that confirm, as others have said, that the blast came from behind the barrier? Also the girl seems as if she may have been thrown forward, not back, although this is less conclusive without knowing exactly how long after the blast this pic was taken. (Judging by how people are running away it would seem to be only seconds after the detonation.)
