Sounds like they may have used an LRAD to hit them with Infra-sound: Infrasound refers to sound waves with frequencies below the threshold of human hearing (20 Hz). These low-frequency sounds can be generated by both natural phenomena (like earthquakes and volcanic eruptions) and human activities (such as heavy machinery and transportation systems).
-Physiological Effects 1.Nausea and Discomfort: Exposure to infrasound has been associated with feelings of nausea, malaise, and discomfort. Studies indicate that when infrasound pressure levels exceed about 50 dB for extended periods, individuals may report these symptoms. 2. Vestibular System Impact: Infrasound may affect the vestibular system, which is responsible for balance. This can lead to dizziness or balance issues, similar to the effects of motion sickness.

The feds should use this in Minneapolis.
