Haha.. I was thinking that although when I did it, I was one of the lucky bastards just sitting there smiling when they told us to take masks off. It affected me, but not much. Then the dreaded "GAS GAS GAS!!!" on excercise and I'd get in trouble for not being fast enough cause I really didn't give shit lol
If they had of jumped in using the foam a.k.a 'party pack' it would have made for a much more spectacular display. It also would have limited the number of people suffering secondary exposure. The foam is also a bit stronger. The spray has a 5% concentration of oleresin capsicum where the foam is at 10%. The foam however doesn't get into the respiratory system. It sprays out like hair mouse but with much greater force and a wider 'splat' like effect.
There were police in front of him though, he sprayed over their shoulder then did a little runner up the steps...While the other police didn't move.
that is just a riot control tactic the line is not to be broken the officer who used the spray would have been in control of that section and is his job to use the spray and get back.
