Not necessarily the "down the throat" but the photos of what we see (police blasting pepper spray at sitting protestors) is actually the safest thing to do once the order to disperse has gone out. The only other option is to attempt to physically manhandle the protestors, and attempt to carry a struggling person. The possibility for permanent injury or disability is MUCH higher in that situation.
Moving an alert peaceful protestor:
broken bones, cuts, scrapes,
Using and moving a peaceful protestor sprayed with Pepper spray:
Same as above except protestor can't see approaching dangers to avoid a curb, tree branch, etc.
asthma, resp distress, choking on nasal discharge, vomitting,
resp arrest(severe reaction)
Lets see worst case
1st example; broken hip or smaller bones
2nd example: death, brain damage, prolonged hospital stay.
Health Hazards of Pepper Spray
just to note:
It is physically impossible for a street cop to force open the teeth without a special tool. Thus forcing someones mouth open and spraying it down their throat is an exageration. Possibly as a protestor gasps for breath they spray it, but not forcing open their mouth. Much worse then "forcing open", because they suck in air as the spray is used.
Proof: the fingers cannot force open a jaw(as the comercial says, 200lbs of preasure on teeth.)
Pepper spray will not move protestors, being blinded and having trouble breathing will not make it any easier to move a protestor.
If they fight off police trying to move them, then it will help.
It abuse of force to pepper spray peaceful protestors.
I do not support thier cause, but these incidents actually make me consider going to a protest.
Goverments need to stop martyring the protestors. Use the least amount of force to get the job done. Most "peaceful" protestors will listen to reason, if they are told to move because of the nasty conditions, they will probably move. Tell them to go home and not protest, they will lock down and refuse to move.
If needed, taser the people that refuse to unlock arms, after informing them they are being arrested. Because at that point they are resisting arrest by not complying.
