Boston Bombs Might Have Been Traceable If Not For the NRA

[jclalor 12]

I wonder if they will finally change their minds.

(A) You don't even know that the marathon bombers used gun powder. That is a guess on your part. Your article linked to JSOnline to support the gunpowder claim, but the only mention of gunpowder in the JSO article was the title. Way to have no facts there, buddy.

(B) You took a question "Did NRA Lobbying Prevent the Investigators From Having a Key Piece of Evidence? " which is by itself ridiculous, and turned it into a certain statement that the bombs are not traceable due to NRA, which is bordering on idiotic.

You imply they are not traceable because there are no tags. Are you dishonest or naive?

note that this came from the Politics section, not the news section.

And we're talking about potential technology, not something that actually exists, or that the NRA has any power to prevent.

I question how effective it would be given the sheer amount of black powder sold and used.

And how piss easy it is to make. Oh and the article calls it a high explosive... really? Can you really not be arsed to even do any basic research into what you're writing about?

The technology is 30 years old and has already been tested and used to solve a bombing, the NRA helped prevent its full implementation.

It's been tested and works fine. So does analysis of the material without taggants. Also, please stop misleading people. The taggants in the McFillin/Allen case were used as evidence, but they did not lead LEOs to the suspect. LEOs already had the suspect before the taggants produce results usable in the investigation. They merely were used to track the explosives back to manufacturer and dealer. It helped seal the conviction in court, but was not the vital investigative tool you are implying. The same things could have been done (and is regularly done today) by checking records of dealers to see who they sold to. Finally, you need to accept that gun powder is significantly different from the explosives those studies considered. First, modern powder is not what you would call an explosive. It deflgrates, which basically means it burns. It doesn't qualify as high explosive. Also, it is sold in such high quantities that tracking it would be prohibitively expensive.

It's a "low explosive". There is a very clear definition.

Some of the reporting in the last few days reminds me of the "exploding Bic" stories, not to mention your beloved rocket engines.

wikipedia: explosives
By velocity
Low explosives

Low explosives are compounds where the rate of decomposition proceeds through the material at less than the speed of sound. The decomposition is propagated by a flame front (deflagration) which travels much more slowly through the explosive material than a shock wave of a high explosive. Under normal conditions, low explosives undergo deflagration at rates that vary from a few centimeters per second to approximately 400 metres per second. It is possible for them to deflagrate very quickly, producing an effect similar to a detonation. This can happen under higher pressure or temperature, which usually occurs when ignited in a confined space.

A low explosive is usually a mixture of a combustible substance and an oxidant that decomposes rapidly (deflagration); however, they burn more slowly than a high explosive, which has an extremely fast burn rate.

Low explosives are normally employed as propellants. Included in this group are gunpowders and light pyrotechnics, such as flares and fireworks, but can replace high explosives in certain applications, see gas pressure blasting.

High explosives

High explosives are explosive materials that detonate, meaning that the explosive shock front passes through the material at a supersonic speed. High explosives detonate with explosive velocity ranging from 3 to 9 km/s. They are normally employed in mining, demolition, and military applications. They can be divided into two explosives classes differentiated by sensitivity: primary explosive and secondary explosive. The term high explosive is in contrast to the term low explosive, which explodes (deflagrates) at a lower rate.

The difference has to do with speed of decomposition. High explosives detonate. Low explosives do not.

Also, I wouldn't suggest trying to make that dynamite. Organic absorbers like sawdust make it extremely unstable. Ammonium nitrate is not hard to come by and much safer, though still perfectly able to blow your head off. There are plenty of other explosives that can be DIY kitchen projects that are significantly less unsafe. (it's hard to call an explosive "more safe" to folks who've never built one).

Ban Fireworks!

So, now that it looks like they got the boom from fireworks (and we've explained why taggants are a horrible idea), would you care to revise your attack on the NRA?

We'd have a great thread if the fireworks bombs were loaded using bits of spoons for shrapnel...

Only if they drove to the marathon, and the bomb making process had something to do with swimming pools.

I know,

why don't we just require "coupons" like at the recent presidential inaguration??

For every one that is within one mile of the finish line???

But what do I know, "I only have one tandem jump."
