School shooting in CT, 18 kids 8 adults dead.

[Shell B]

nope, you're also horribly wrong.

You're prematurely assertive.

Leave it to educated people to know jack shit about the FBI/NSA and it's techniques to tracing materials used to create explosives.

I'm not educated, but that's irrelevant here. I'm sorry, Moros, but I don't know what world you live in where legislation somehow translates to reality. Something simply being traced doesn't make it hard to obtain. Furthermore, if you are going to assure, you're going to have to provide proof that you know more than jack shit, not just run on the assumption that you know more.

Explosives that can be made easily in bulk through common house hold items are actually tracked and logged.

Really? I have never, ever once had my purchases tracked and logged. Common household items are common. That is the point. I could store hop for three fucking states and no one would even be mildly suspicious of me.

When a person of interest purchases enough within an unusual interval, they flag themselves to the FBI and NSA for further investigation.

How? Grocery stores are not linked to the FBI.

Given the estimates that the FBI and NSA are still ten to thirty years ahead of the consumer market when it comes to numerical analysis (the biggest employer of mathematicians is the FBI btw), pattern analysis, et al, it would stand to reason that they're actively preventing that which you described.

Explain how people still do it then, please. Every fucking meth lab in the country is a bomb waiting to go off. How is it still happening?

All considered, the hardest bomb to predict via usage rates, a fertilizer bomb, can be tracked through noting the uptake of fertilizer across several locales and cross-indexing it to the distance possibly covered by a set of one to few individuals operating in a cell mentality.

There is no fucking way in hell that is going to work in even most instances. At least with guns (and I'm not picking a side in that argument), they may be registered to someone. When was the last fucking time you had to provide your information to buy fertilizer. I could buy one bag of fertilizer from every farm in Massachusetts in a matter of days. Don't use a credit card. Wear a hat. It's one fucking bag. Nope. Sorry. Nope.

Once again, this is mathematics land, but not impossible to do.

No, no. It is not about what's possible. Most things are possible, I think. What matter is if it applies to reality as of right now. Like I said, people choose guns over other easier methods (maybe said that part in another thread). However, those easier methods are still easier and nothing you have said makes it sound any different. "They can and might use math to get you if you don't have half the brains of an average adult." does not mean "They catch most people who try to make bombs by superior detection skills that you do not possess, oh puny laymen."

On an off note, I've often wondered how often the security agencies actively seek out people who would create explosives, furnish them with enough and then bust them.

Bombs go off all the time. Homemade bombs. I hope they aren't furnishing those explosives.
