I think Uncle Sam DEFINITELY did it in the Lagoon with The Pulsed Microwave Radar

Evidence for Increase in Dolphin Standings Due to Pulsed Electromagnetic Radiation from Radar Stations (FAA, Weather, Military & Private Doppler Radars) Grounding out into the Ocean Water

The areas along our coastlines with the highest amount of pulsed microwave power density appear to agree with the locations of these four unusual mortality/stranding events in dolphins.

Areas of the country along coastlines with the highest atmospheric pulsed power density from radar stations have the highest incidence of dolphin strandings.

He even left his microwave radiation fingerprint.  But will he admit to it?
