You known how people always say to drink milk if you've eaten something too spicy and want to reduce the burning? That's because milk proteins bind to capsaicin and help to carry it away instead of leaving the molecules free to irritate your tissues. As the name suggests, pepper spray consists primarily of concentrated capsaicin.
When you're dealing with large numbers of pepper spray injuries, milk is indeed an important medical supply, since that's generally going to be the most effective form of first aid available short of setting up an actual field hospital (which isn't the most plausible idea right now). Water is also important for washing wounds and treating people that have been exposed to tear gas, to say nothing of treating dehydration (a very real risk in summer temperatures). Arguing that these were medical supplies is very, very easy.
So what were the crackers and hairspray for? ---
