Are you looking at these via your phone or something? I can see all 57 images just fine.

Computer. I didn't scroll down. Now I see them all. Your guess may be as good as mine. Hard to say as I was not there.
 
My guess is the drop probably wasn't made near the time of explosion, too much traffic on that sidewalk it could be at a stand still for quite a while. I'll bet the store video shows someone doing it when the traffic is moving, before the race perhaps.

Was there a fense around NY city?

lol of course. very heavy security and tons tons tons of barriers. very limited subway stops too. limited points of ingress and egress too.

How could they stop everyone who had a backpack from entering?

simple - fences and thousands of police officers + National Guards + bunch of agents from 3-letters agencies

That is not Kosher. If that does happen the person or family member should be asked if it's OK to use pig blood . I am not Kosher but I don't think I would
pig blood in me.

I wouldn't want a human-compatible pig's blood inside me either.

Yes. But, that is on a military base correct? There is an entry point for Patriot Point in SC, right?

For something like NYE no such entry point exist for a major city. And, if they tell you to leave and you live in the city where would you go?

a city has blocks. there are fences and police officers controlling points of ingress & egress traffic.

in NYC, entire Broadway street are blocked with fences. you cannot cross the street until you reach a certain location where you can cross the street. subway stations are locked. every few blocks will have a checkpoint with officers checking and inspecting people to see if they've got backpacks or not.

hotels on same street will have police officers at the front door telling them that they'd have to leave backpacks in their rooms.

why don't you check out youtube and watch some New Year videos. you will see that nobody's carrying backpacks.

You had no idea what I heard in my life, Shrapnels is still worse because it goes beyond the distance of shockwave. My former Dean of Student, himself is Deaf and had his hearing son who signed up and went to war with Iraq, his dad begged him not. His dad was deeply opposed to gun, and any weapons and of course closed minded. Since his son already over 18 yrs old, nothing his dad can stop him.

He was not near the explosion but shrapnel penetrated into his chest and it was very tiny shrapnel. He didn't feel a thing for a good while then got sick with infection, send back to America, 2 months later I think he died from infection from tiny shrapnel.

And don't you know why most hand grenade got plenty of glass and metal shrapnels in it. Why bother put them (Shrapnel) in grenades if shockwaves is worse than shrapnels?

==================
Blast injury - Wikipedia, the free encyclopedia

Read second paragraph

Primary injuries
Primary injuries are caused by blast overpressure waves, or shock waves. These are especially likely when a person is close to an exploding munition, such as a land mine.[2] The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract. Gastrointestinal injuries may present after a delay of hours or even days.[2] Injury from blast overpressure is a pressure and time dependent function. By increasing the pressure or its duration, the severity of injury will also increase.[2]
In general, primary blast injuries are characterized by the absence of external injuries; thus internal injuries are frequently unrecognized and their severity underestimated. According to the latest experimental results, the extent and types of primary blast-induced injuries depend not only on the peak of the overpressure, but also other parameters such as number of overpressure peaks, time-lag between overpressure peaks, characteristics of the shear fronts between overpressure peaks, frequency resonance, and electromagnetic pulse, among others. There is general agreement that spalling, implosion, inertia, and pressure differentials are the main mechanisms involved in the pathogenesis of primary blast injuries. Thus, the majority of prior research focused on the mechanisms of blast injuries within gas-containing organs/organ systems such as the lungs, while primary blast-induced traumatic brain injury has remained underestimated. Blast lung refers to severe pulmonary contusion, bleeding or swelling with damage to alveoli and blood vessels, or a combination of these.[3] It is the most common cause of death among people who initially survive an explosion.[4]
[edit]Secondary injuries
Secondary injuries are caused by fragmentation and other objects propelled by the explosion.[5] These injuries may affect any part of the body and sometimes result in penetrating trauma with visible bleeding. At times the propelled object may become embedded in the body, obstructing the loss of blood to the outside. However, there may be extensive blood loss within the body cavities. Fragmentation wounds may be lethal and therefore many anti-personnel bombs are designed to generate fragments.
Most casualties are caused by secondary injuries.[5] Some explosives, such as nail bombs, are deliberately designed to increase the likelihood of secondary injuries.[5] In other instances, the target provides the raw material for the objects thrown into people, e.g., shattered glass from a blasted-out window or the glass facade of a building.[5]

your link just proved my point. that's why our soldiers are dying from IED blast even when inside armored vehicles.

why? shockwave.

shockwave kills, shrapnel usually does not. that's why only 3 dead and 150+ injured.

Invite VG to visit NYC. :D

Boston to NYC isn't far, I think so.

I've been to NY. It's a nice city.

In fact, I as there on 4th of July and there were backpacks.

Oh I see, on Time Square?

I only remember about backpacks are banned on New Year.
