2. Put me down for $50 if you start a defense fund. I'll also raise funds on my blog if you need it.
Indeed it is "CS" gas. The container it is in resembles those carried by LEOs complete with leather case and metal clip to fasten to your belt. This one is about 8" in length, slightly bigger than current police issue.
