Via Stl. Today:
Two men indicted last week on federal weapons charges allegedly had plans to bomb the Gateway Arch — and to kill St. Louis County Prosecuting Attorney Robert McCulloch and Ferguson Police Chief Tom Jackson — the Post-Dispatch has learned.
Sources close to the investigation were uncertain whether the men had the capability to carry out the plans, although the two allegedly did buy what they thought was a pipe bomb in an undercover law enforcement sting.
The men wanted to acquire two more bombs, the sources said, but could not afford to do it until one suspect’s girlfriend’s Electronic Benefit Transfer card was replenished. […]
One of the defendants’ plans, the sources said, included planting a bomb inside the observation deck at the top of the Arch. It was not clear how they could have gotten a bomb past airport-style security screening for rides up.
