The falling culvert theory is not breaking news. It was considered a possibility from the word go. Responding agents damn near took a header as they approached.
The people claiming rocks were used don't have anything to do with the investigation.

Maybe, maybe not. Sources close to there say it was an attack. Ambush was the word they used. Maybe they pushed the agents into a concrete drainage ditch, or any number of scenarios. Until an official press release comes out, even my buds with the BP 30 miles from there don't know all the details.
