The Senator's Letter made the headlines here in Tampa Bay Area, today's Times... Hadn't heard the Pres got one too. (Maybe the Media's trying to avoid the usual "Copycat Crimes" that often happen after some Idjut makes National Headlines...) Good for them if it's the case..tho I'm a Doubter...

I once read-up on Gunpowder. More'n-Likely, what was used was Made-in-USA... All the powder made in the USA carries microscopic "Markers" (Some of which DON'T-Burn when Ya hear the BOOM...) and the FBI Hoovers-Away at the Crime Scene, identifies the Markers, & then starts tracing The Buyer(s).

Poor choice of Explosives..on the Would-Be Terrorists..this time around.

One of my Sheriff Buddies is the Local Bomb Squad "Point Man"...(HAS a good sense of humor, I'll add)...and...he's pretty Busy-These-Days...already. Been at it for Years/Paper here's never run a single Story on him. (Good for the Media..locally!)

Yeah, already LOTS of Crazies out there... But also lots of well-trained Bomb-Sniffing Pooches too... Prolly shoulda run a few through Boston..but 20-20 Hindsight's not always the answer.

Neither is gettin' all-Paranoid and sayin' "There's Nothing We Can Do."

Best Wishes, Big Guy-Hug,
