A camera phone is your best protection against police abuse.<p>Make a 50% mixture of Malox ant-acid and water. If you get hit with OC (not CS), have a friend pour a little into each eye. Spraying it with a squirt bottle on exposed skin offers some relief also.<p>3M painter's masks make excellent and cheap gas masks. Have it assembled and fit to your head before you leave the house. The OC floats around and often is invisible. DO NOT WEAR CONTACT LENSES!<p>Put a newspaper in your backpack. If the police start shooting their paint balls, flip your backpack around and wear it on your chest like a breast plate.<p>Never, ever touch the police as this is a felony assault.<p>If asked if you have a permit, say yes it is in my pocket and it is a copy of the Constitution.<p>Solidaridad!!!
