take pictures. The four cops attacked demonstrators and participated in arrests as well as marched with protesters. There was a bit of conflict during the march with a few scuffles and a mounted cop spraying down a crowd (including small children) with OC spray without provocation. Video, more pictures, and a full written account is available by the excellent Phoenix Class War Council.
Anyone with information on the identities of these officers (in order to make sure they don't show up to meetings or more demonstrations) is encouraged to email snitchwire [at] riseup [dot] net.
