The NYPD is using Military Grade Sound Cannons on protesters. The decibel levels can reach up to 162, which is 30 decibel levels higher than the average human threshold. Capable of causing permanent damage. Please share this around and let people know just how vile the NYPD is and how they are treating their citizens. My cousin who is in these protests has experienced it herself. This is cruel, inhumane and unlawful treatment.
