Reply #4: It's because there was never any threat due to this

[htuttle]

Here's how it actually went, according to more thorough news sources (ABC, CBS, etc...):

1) Undercover FBI officers approach this guy they know of as an arms dealer, and ask him to obtain SAM missiles for them.
2) Arms dealer goes to Russia, where another undercover agent, this one working for Russian police, sells him a fake missile, and suggests that he could use it to shoot down Air Force One.
3) Russian undercover officer ships fake missile to US, and arms dealer is arrested on his return.

So, there wasn't really a plot, or a threat, or anything but a criminal arms dealer willing to sell stuff he shouldn't for a buck. One shady arms dealer down, 500,000 more of them to go (give or take a few hundred thousand).
