Capitol Police Throw Flashbangs On Peaceful Crowd (January 6, 2021)

There were multiple reports of Capitol Police throwing two flashbangs into a crowd of completely peaceful Americans citizens protesting the fraudulent election on January 6.

It is alleged that these first two flashbangs were thrown into the crowd 15-20 minutes before any violence started.

Is this the proper way to use stun grenades on a peaceful crowd of protestors❓
