While local police are banned from using chemical irritants because of the danger they pose to the public, federal units operating in our city are using a loophole to deploy a poison that toxicity experts warn causes permanent lung damage and cancer.
Likely just a tale.
Baking soda is basic, Which would imply that the chemical being used is acidic so that it’s neutralized with baking soda. This also assumes that they mix in such a way that baking soda actually makes contact with enough of that chemical to have any effect.
All of these are pretty big assumptions that are very easily wrong for many number of devices and chemicals.
