Explosion at Boston Marathon

[K.Mooneyham]

Shep Smith on Fox keeps bringing up Waco. The siege at Waco was on April 19, not April 15.

Why do these anchors have to make these incredibly stupid statements?

He needs to shut his pie hole.

Anygunanywhere

Shep Smith is a weasel. Can't stand him.

I think the folks in that area were very lucky that the bomb wasn't larger - it looked relatively weak (although of course devastating to those nearby).

I suspect a lot of the white smoke and debris thrown in the air was a component that burned but failed to detonate eg. flour.

Flour? Is that to make it like one of those grainery fire/explosions?

Looks more like a black powered pipe bomb or TETP-ammonia type explosion to me, lots of white smoke.

C4 and other "fast burners" (higher RE factor) have a more grey to black smoke.

Prayers out to those effected and those giving aid and support!

[K.Mooneyham]

Yes - a dust explosion, basically. Flour is just a random guess based on the color of the smoke and the relatively low yield, but the explosion certainly didn't look like a formally-manufactured high explosive such as the higher grades of dynamite or military explosives such as PETN, RDX or C4.

I'm guessing an improvised explosive of some kind - from the large flame that erupted, I'm wondering if small propane tanks were used.

I always think of explosives as substances DESIGNED to give off large amounts of energy and/or heat. But what you say makes sense. I consider you the resident expert considering your experiences, so thanks for the informative reply.

I (guess) bet they will "determine" it was black powder purchased from out of state gun stores. (It won't matter whether it really is or not) Thereby they will have to heavily regulate/ban sales of all reloading components. Goes along with the never waste a good crisis thought. I don't trust this current "Justice" department to be honest about anything anymore. Really hope I'm wrong on my guess.

Does anyone remember Obama's decision to allow easier entry for Saudis.

Tragic. Many parts of the world face bombings and I guess we have now graduated to that level. I wonder if this will be the new trend?

Yes - there are low-order explosives which deflragate and high explosives which detonate (supersonic) - basically different decomposition rates. They also differ in terms of their brisance, which really means their shattering power - a factor typically determined by how quickly they reach their peak pressure.

But what you say makes sense. I consider you the resident expert considering your experiences, so thanks for the informative reply.

Not an expert, just a mis-spent youth and some observations

I was "forced" to watch endless replays and slomos at work as everyone packed the break room to see. I was there taking my legitimate break and trying to read, but between the attractive nuisance of the TV that Home Depot provided, and all of the really stupid comments, reading was next to impossible.

One of the slomos of the moment of the blast shows the runner who collapses getting hit, you can see him react, just a split second after the banner lining the fence moved from the blast front and fragments. The smoke appeared to me to be secondary to the explosion and reminded me of something burning not the "high velocity" motion of smoke from an actual explosion, so immediately assumed that the bomb did not detonate completely, and then when I heard that there was a second explosion, I wrongly came to the conclusion that it was an explosion of an amount of leftover explosive from the first bomb, which I have seen happen. I don't really feel like watching it again, but I may have to just to prevent the talking heads from influencing my thinking.

My son-in-law, daughter, and a couple of grandchildren usually participate in the Boston run because of their proximity to the event and they are runners. I am praying for their safety.

More of why I can't stand this guy.

With No Evidence, Alex Jones Calls Boston Marathon Explosions a ‘False Flag’ Operation Conducted by the Gov't http://www.theblaze.com/stories/2013/04 ... %20Buttons" onclick="window.open(this.href);return false; … jh

Well, the Boston Globe did announce a controlled explosion bomb-squad drill at 600 Boylston only minutes before the Boston Marathon explosions. Look at their live feed.

Upon further consideration of the Globe's Twitter timeline, my guess is that they found two of the bombs before two of the others detonated. It's the only possible explanation but it would be something they might keep quiet because of the investigation.

Was Peter Bergen born that stupid, or did he have to practice?

This bears all the hallmarks of Islamic terrorism. Everything from the type of explosion to the large, public event where there would be mass casualties screams "Radical Islam."

Right-wing terrorists -- if there was such a thing, which there isn't despite Big Sis' fondest wishes -- would target government facilities: Federal buildings, IRS offices and the like.

Left-wing terrorists target business interests and capitalist institutions.

There are radical extremists radicals in all cultures, religions, political sectors and even small clubs and organizations. It just depends on how 'radical' they are to a movement. Let's not forget the OKC bombing was domestic. PETA and ELF are just as capable of doing things as Al Quida. I will hold any thoughts of who/what until they have more evidence or a solid suspect. Saying it has all the hallmarks of this or that now is way premature. Pipe bombs with fragmentation components are about as basic as you can get.
