High pressure water can cause injuries, especially eye injuries. I believe tear gas is relatively benign other than possibly for asthmatics. Fully agree with you on the tasers though. They should be just one step below using a gun, not “I’m lazy and don’t want to deal with this person.”

Police usage of CS gas killed a woman this week, she was young (22) with no history of asthma.

Tear gas is not benign, it is nasty stuff that has already killed people. Some preliminary research points to it potentially damaging the lungs of people who are exposed to it for a long time, possibly permanently.

I don't think OP said "high-pressure."

On tear gas, CDC has https://emergency.cdc.gov/agent/riotcontrol/factsheet.asp :

  People exposed to riot control agents may experience some or all of the following symptoms
  immediately after exposure:
  
  * Eyes: excessive tearing, burning, blurred vision, redness
  * Nose: runny nose, burning, swelling
  * Mouth: burning, irritation, difficulty swallowing, drooling
  * Lungs: chest tightness, coughing, choking sensation, noisy breathing (wheezing),
    shortness of breath
  * Skin: burns, rash
  * Other: nausea and vomiting
  
  Long-lasting exposure or exposure to a large dose of riot control agent, especially
  in a closed setting, may cause severe effects such as the following:
  
  * Blindness
  * Glaucoma (a serious eye condition that can lead to blindness)
  * Immediate death due to severe chemical burns to the throat and lungs
  * Respiratory failure possibly resulting in death

Coughing and shortness of breath are especially nasty during the COVID pandemic. And none of blindness, glaucoma, immediate death, or respiratory failure sound especially fun.
