We have also seen the use of tear gas. I don't want the police to hurt anyone, but I haven't seen any long term damage from its use.
If police are going to use force, from what I have seen, tear gas is less dangerous. It is still awful. I'd rather it not be used, but I just wanted to share what I've seen.
Rubber bullets are supposed to be fired at shin height, to achieve the appropriate mix of pain and risk reduction. They’re not zero risk because of ricochets, but flat, low trajectories help. It should go without saying that they should only be used when necessary, but if they must be used there is a way it should be done.
The number of people being struck in the chest and head by rubber bullets implies that the cops are aiming for the head, a gross abuse of force if true.
It’s only the less effective shot shells that are more likely to bounce around and be hard to track.
To put that in perspective, try to make the largest circle you can make with your index and thumb (think OK symbol shape). That's more or less the shape of these things and they are effectively a thin layer of rubber with a solid steel core. The inside of your finger circle is the steel and the thickness of your fingers is the rubber.
Hope this helps.
