Letters containing Ricin

Yikes, letters of poison sent to government officials right after an act of terrorism. This is basically a repeat of 9/11 pattern a dozen years ago. See here for a reminder of the details.

President Obama got one of these. Glad he does not need to open his own letters. See news details here. However, what I don't understand is this. How come no news report tells me what the letters say?

This time it is ricin. There are so many deadly plants and things out there, and people thought about this as chemical weapon. Poison is supposed to be banned in some national treaties that nobody follows anyway. Ok it is harsh to kill with chemical weapons of mass destruction. Is it not harsh to kill somebody with a machine gun?

I hope we soon get to the bottom of the poison letters and to the Boston bombing.
